For the last week, I’ve been busy preparing for my classes at Walden School, including inventorying the science lab room (which is also my classroom) and planning out my course schedules. I’ll be teaching two sections of Chemistry, one of Astronomy, one of Computer Technology (a basic computer literacy course required in Utah), a section of Media Design, and a section of Video Production. This is, for me, a perfect schedule. In the meantime I’ve also been preparing a series of maps and 3D images of the Tintic Mining District, focusing on the ore deposits and the various mines located there. I’ve also prepared the script for this section of the video, which I have pasted below:

Tintic Geology

To understand how the ore bodies in the Tintic District were deposited, we have to start about 800 million years ago in the Precambrian Period when the western portion of the North American craton rifted away from the rest of the continent along a line where the Wasatch Front now lies – this Wasatch Line has been an important hinge line in Utah’s geology ever since. For the next 600 million years, a sequence of ocean sediments including dolomite, limestone, shale, and sandstone were deposited off the coast in the geosyncline that would become western Utah. Beginning 150 million years ago, Nevada and then western Utah were uplifted as the Farallon tectonic plate was pushed under North America. Like a throw rug being wrinkled up as it’s pushed over a hardwood floor, western Utah was folded by thrust faults into a large mountain range during the Sevier orogeny about 70 million years ago. This thrusting continued across eastern Utah and into Colorado and Wyoming during the Laramide orogeny, building up the Uintah and Rocky Mountains.

East Tintic Mines

Then, about 50 million years ago, the Farallon plate began to collapse from underneath the continent. As it peeled away, a wave of volcanism moved from east to west across Colorado and Utah. Intrusive laccoliths rose to the surface, bulging up the LaSal and Henry Mountains in eastern Utah and forming explosive calderas in several places in western Utah. About 35 million years ago, a series of calderas formed in the area that would become the Tintic Mountains. A large andesitic volcano rose up from eruptions of ash and tuft.

Tintic Standard ore samples

About 31.5 million years ago, the volcano collapsed as the intrusive magma began to cool. Mineral rich fluids were injected into the surrounding limestone, quartzite, and dolomite as replacement beds. The hot magma caused the carbonate rocks to decompose; for example, limestone turns into lime or calcium oxide and carbon dioxide gas when heated. This left large cavities that then filled up with the mineral-laden magmas. These deposits are called stopes, such as the famous Oklahoma stope of the Chief Consolidated mine. The carbon dioxide released from the decomposing limestone and dolomite in turn dissolved into the hot magma, making it a kind of lava champagne, and reacting with it to form various exotic minerals, some of which are found nowhere else.

The primary ore-bearing minerals in the Tintic District are enargite, tetrahedrite, galena, sphalerite, pyrite, marcasite, and native gold, silver, and copper. But many more minerals are present, including unusual minerals that blend copper, silver, tellurium, arsenic, sulfur, carbonates, hydrodixes, etc. At the Centennial Eureka mine, over 85 different minerals have been identified, ranging from common pyrite, malachite, and azurite to minerals found only here. It is the type locality (where the mineral was first identified) for leisingite, frankhawthorneite, jensenite, juabite, utahite, and eurekadumpite. Other rare minerals include xocomecatlite, carmenite, adamite, duftite, and mcalpineite.

These mineral deposits occurred around the edges of the caldera and formed the five large ore zones of the main Tintic District. The Gemini Ore Zone runs to the west of Eureka south to the north edge of Mammoth Gulch. The Gemini, the Bullion Beck and Champion, the Eureka Hill, and the Centennial Eureka mines (known collectively as the Big Four) are located on this zone.

The Chief-Mammoth Ore Zone begins under the center of Eureka and extends due south across the mountain to the east end of Mammoth Gulch. The Chief Consolidated mine is located on the richest ore body, which is right under the center of Eureka city; up the hill is the Eagle and Blue Bell mine, named for the beautiful deposits of azurite found inside. Further south over the top of Eureka Peak lie the Grand Central, Mammoth, Apex, and Gold Chain mines that are also part of this deposit.

Ore zones in the Tintic District

Ore Zones and Major Mines of the Tintic Mining District

The Plutus Zone branches off of the Chief-Mammoth Zone high up in the Tintic Mountains. The Godiva Zone starts just east of Eureka and runs southeast in a curve where it joins the Iron Blossom Zone, which continues in a curve south and then southwest. Some mines in these zones include the Godiva, May Day, Humbug, Beck Tunnel, Sioux, and Iron Blossom mines.

In the eastern section of the Tintic District, several zones of minerals were deposited and were among the last to be discovered because they are overlain by 400 feet of igneous rock. These bodies include the Burgin ore body, the Tintic Standard, and the North Lily bodies. Other bodies are located at the Apex and Trixie mines.

In the southern section of the Tintic District, the large replacement bodies give way to smaller fissure veins that are only two feet wide on average but can be up to 4000 feet long. Here, the mineral-bearing magma was injected into cracks and fault lines already existing in the host rocks. The Dragon mine is the only true open pit mine in the area; it sits on top of a network of fissure veins at the south end of the Iron Blossom Zone. Other mines in the area include the Swansea and Sunbeam mines at Silver City, the Tesora and Treasure Hill mines at Ruby Gulch, and the Showers mine at Diamond Gulch.

The final chapter in the area’s geomorphology began about 17 million years ago when normal faulting created the Basin and Range province, lifting up blocks to form the mountain ranges of Utah and Nevada, including the East Tintic Mountains. Other blocks sank to form the valleys, such as the Tintic Valley. Erosion has exposed the ore bodies in many places, including the outcropping that George Rust stumbled over in 1869. It was to become the Sunbeam Mine.

Replacing topsoil Eureka Utah

Replacing topsoil in Eureka, Utah

On my visit to the area around Eureka, Utah last Friday, June 4, I not only wanted to visit Mammoth and Silver City, but to also document the efforts by the Environmental Protection Agency to clean up the town. I had traveled through Eureka a few days before on Memorial Day and noticed that the lawn and soil around the LDS chapel in Eureka was being dug up to a depth of about 18 inches. On Friday, crews were in the process of bringing in new soil in dump trucks and spreading it over a layer of black plastic where the lawns used to be. Normally I wouldn’t have noticed it much – just chalked it up to them putting in a new sprinkler system or something similar. But I knew differently. This was the latest site in an ongoing process to replace the topsoil throughout the entire town, which is a huge undertaking. All the old mine sites throughout the district have left a legacy of environmental contamination and pose a danger to careless explorers who try to enter mine shafts or tunnels or ruins.

Ore dump at Dividend

When silver ore was discovered in the East Tintic Mountains by George Rush in 1869, it ignited a stampede of mining claims that spread throughout these mountains. New deposits were soon located and claimed, and the ore was assayed to be rich in silver, gold, lead, zinc, copper, and other minerals, usually in the form of metal sulfides. The most level sites near the mines quickly grew into the towns of Eureka, Mammoth, Silver City, Diamond, Knightsville, Dividend, etc. These towns were usually as close to the mines as possible so the miners didn’t have far to walk, so that miner’s houses and the mine buildings, hoists, smelters, railroad depots, and city businesses all competed for space in the narrow canyons. Tailings dumps of discarded minerals and slag from the smelters covered the hillsides around and above the town. Dust from these piles was blown by the frequent winds (this is western Utah, after all) and blanketed the whole town. Nobody thought much of it at the time. It was all just part of life in a mining town. But the entire topsoil was contaminated with lead and other metals down to about two feet under the surface.

Today, the EPA has identified the area around Eureka as a SuperFund site, spending millions of federal dollars to clean up the contamination.  One by one, the yards of the residents and businesses are being dug up and the soil replaced, brought in from a staging area east of town. To prevent the tailings piles from blowing more toxic dust around the town, broken limestone rocks called rip-rap are being hauled in from a nearby quarry and are carefully placed to cover over the tailings piles to prevent further erosion by wind and water.

The work is progressing throughout Eureka, but the entire mining district has the same problem. Recent exploratory work has dug up the tailings piles in Silver City again, leaving the yellowish sulfides once again exposed to erosion. Many of the mine sites in the hills are owned by small-time private owners who keep the mines open on an occasional basis. They don’t have the resources to prevent the erosion of their tailings piles, and much of the East Tintic Mountains is contaminated just as Eureka itself is.

Old mine shaft

Abandoned mine shaft at Dividend, Utah

Another problem in the area is the many abandoned mine tunnels and shafts. Mines today are required to provide reclamation funds before the mine can even open, but it wasn’t an issue in the 1800s and early 1900s when most of these mines were active. The owners took the ore from the hills, then left all the scars, holes, pits, slag, tailings, and buildings behind when the ore ran out and their companies closed. Now these ruins are a hazard to casual explorers; every year or two someone dies falling down an abandoned mine shaft in Utah. The state has begun a program to close off these mines; to place grates or metal doors in the tunnels and shafts or to blast the entrances closed. Over 8000 mine sites have been closed off throughout the state through this program, but many, many more remain to be done.

Knight Smelter at Silver City

Ruins of the Knight Smelter at Silver City, Utah

Smelting or concentrating the ore brought its own environmental problems. Jesse Knight, the silver magnate that started Knightsville just southeast of Eureka, also built a smelter at Silver City in the early 1900s that operated for about eight years. The foundations of this smelter still remain, as do residual chemicals used to concentrate the ore, including mercury. When I visited the site on Friday, I found a man and his two young girls exploring the site. I suggested that he wash off his girls’ hands and shoes carefully once they were done because the whole site is contaminated with mercury (June McNulty, who runs the Tintic Mining Museum in Eureka, told me that he used to play with pools of liquid mercury metal that would seep into pockets around the smelter).

Right to the south of the old smelter lies a large heap of grayish tailings, now slowing growing a crown of weeds and grass. All the tailings left from the Knight mill were scooped up in the 1980s and placed on a pad with drainage pipes running through the pile, then a solution of cyanide was pumped and sprayed over the pile, leaching its way down through the tailings and chelating with the remaining gold and silver. The ore from these mines has been worked and reworked to get every last fraction of value out of it. But now the pile has been left just like all the other piles around, but with the addition of cyanide. I don’t know if steps have been taken to reclaim the pile, but I wouldn’t want to walk around on it.

The efforts to clean up these environmental messes is necessary, but it does come at a cost beyond just money. To clean up the town and make it safe to live in, its essential history and character has been changed.  The heavy equipment moving in limestone and soil has shaken apart a number of fragile historical structures, including buildings, homes, and headframes. Where there were colorful tailings piles slowly returning to nature, there are now carefully constructed fresh piles of gray limestone rocks, an ideal hideout and breeding ground for rattlesnakes (no joke here – I ran over one in my minivan as I was driving up the road to Mammoth). Eureka doesn’t look the same as it did ten years ago.

One can argue that Eureka must be dynamic and capable of changing. It’s not a museum but a living town, and change is part of life. But the historian in me hates to see history destroyed in the process. That is one of the main reasons I’ve started the Elements Unearthed Project and have traveled to Eureka several times in the last few years with my cameras and equipment; as the EPA clean up progresses, the town is changing and I want to preserve what can be preserved of the history before it’s gone forever.

The beryllium video second half is progressing well. I’ve decided to do the three episodes on the TIntic Mining Districts next instead of blown glass because It’s fresh on my mind and I now have all the footage and photos I’ll need. My goal is to get the beryllium video done and uploaded by the end of this week, then the Tintic videos by mid-July. Then I’ll start hitting the streets looking for financial sponsorship to continue this project.

The last few weeks I’ve had to neglect the Elements Unearthed project in order to finish a client video that had a tight deadline. It was uploaded to YouTube Thursday night, so I now have a little bit of a breather before the next project and am back at work on Part 2 of the beryllium video. Winter has finally decided to let go (after one last gasp – we had a snowstorm here just two weeks ago), and already the early summer heat is drying out the cheat grass and turning it a brownish-purple color on the lower south-facing slopes. I decided now was the time to do some exploring and photography while the grass is still green in the mountains.

Over the last two years I’ve visited the Tintic Mining District several times with students and my own children and have collected a considerable amount of photos and video clips, including a tour of the Tintic Mining Museum and an interview with June McNulty, who runs the museum with his wife. But there were several places in the district that I hadn’t visited, including Mammoth and Silver City. So yesterday (Friday, June 4) I packed up the cameras and headed for the hills.

I stopped first in the hills above Burgin, the site of the town of Dividend, so called because the mine paid out fairly decent dividends to the miners compared with other mines in the district. I decided to climb up the hill further than before, toward the two large rusty tanks that can be seen from the road. I was surprised to find much more there than I had known about before, including the ruins of miner’s houses (some semi-wild purple irises and lilacs were still alive and blooming). A processing plant once existed here, and the ground is covered with yellowish-stained rocks and pieces of slag and everything smells of sulfides. One ruin 2/3 up the hill still has an old rusted stove for keeping the miners warm in what was probably the change room – the mine portal itself is just above the room, and there are even a few remains of timecards used to clock in and out of the mine. The few I looked at were dated from 1971, which was about the time that the mine at Dividend finally closed down. Mining continued, periodically, further down the slope at Burgin. Almost forty years of weather has taken its toll; all the roofs and any other wooden structures have long since rotted away, leaving old, dry fragments of boards with rusted nails sticking out littering the ground. Most of the equipment is gone, taken by looters and souvenir hunters, but enough of the foundations and structures remain that one can imagine what Dividend looked like in its heyday.

The road past Dividend is off the main path of Highway 6. It’s a good road, well maintained and asphalted but not much visited. I only saw two other cars and a motorcycle during the four hours I spent exploring along the road. The East Tintic Mountains between Dividend and Eureka are dotted with old mining ruins and tailings piles, with dirt roads leading off frequently up every side canyon and ridgeline. Most of the area is posted No Trespassing, so I limited myself to taking photos from the main road. It is still late spring up there; the maple trees in the canyons have only just gotten their leaves, and wildflowers including mountain lupine and Indian paintbrush cover the hillsides.

I traveled through Eureka and saw the continuing cleanup efforts there (more on this in my next post) and drove on to the town of Mammoth. Located in a side box canyon just to the south of Eureka, this was one of the richest areas of the Tintic Mining District. The mines are located ringing the valley – many long since abandoned but several showing recent work. With prices for gold and silver high right now, much exploration is underway to re-work the old claims and tailings piles and to do new exploratory drilling. Again, most of the area is posted and is private property; I limited myself to the main streets of Mammoth to photograph the old buildings and mine dumps.

Mine at Mammoth Utah

At one time, when the processing plant was in full operation in the early 1900s, Mammoth boasted a population of about 2000. The people lived in the upper eastern portion of the canyon (Upper Mammoth) while the mill was at the mouth of the canyon lower down the slope (called Robinson after the mill’s foreman and later Lower Mammoth). Once the town was incorporated, public works such as churches and even a hospital (rare for a mining town) were built in the middle, or Midtown. In the early 1930s, my father used to visit his first cousin Ralph Larsen, whose family lived in Mammoth. During the winter the road leading up to town would be covered in packed snow, and the two of them would ride their sleds from Upper Mammoth all the way down to Highway 6, almost two miles, without ever stopping. Then they’d have to wait for someone to give them a lift back to the top.

Even though the mines had all closed by the 1950s, Mammoth somehow escaped the fate of most boom-and-bust mining towns; it never completely died. A few people hung on. Over the last ten years, since I last drove up here, it even appears to have grown in population. More houses have been fixed up and are occupied than before, and it is becoming an artistic community of sorts. Renewed interest in mining has also given the town a boost.

After Mammoth, I visited the old Jesse Knight smelter at Silver City and drove up the canyon there, but I’ll leave that for next time.

This blog has reached a milestone over the last week. Over 15,000 people have visited this blog since it was begun in Oct., 2008. Since my fellowship in Philadelphia last summer, the viewership has risen greatly, and I’ve been averaging over 1500 visitors per month with 2600 in March as my top month. I don’t know how that compares to other blogs out there, especially on such an esoteric topic as the origins and uses of the chemical elements, but it represents to me that my purposes in creating this blog are being fulfilled – people are finding out about the Elements Unearthed project and are hopefully learning about the elements (although this is impossible to assess using just the WordPress stats).

Monthly Blog Stats

Stats for The Elements Unearthed blog

I can’t track demographics about the age or interests of the visitors except by looking at the most common search terms they’re using. Some of the time the searches bring people here accidentally – for example, they might be looking up how to build a water turbine and find my post on the water turbines used at the Du Pont Gunpowder Factory in Delaware. I don’t have any instructions that would be useful for them, and their purpose wasn’t to find out about how gunpowder was made, but here they are. A rough estimate is that about two-thirds to three-fourths of the people coming to this blog are doing so because of legitimate searches involving chemistry, the elements, or the history of science or mining. I hope that I have provided the information they need.

I get a few searches every day about the Tintic Mining District around Eureka, Utah. This is probably because not many other sources exist. Some of the comments written show that some of these visitors had relatives that worked there (so do I – one of my great grandfathers died as a result of injuries received as a miner in the town of Diamond, part of the Tintic District). This lets me know that I need to soon do the episodes on the Tintic District. Now that the weather is (mostly) getting better, I hope to take one final trip to the area around Mammoth, Diamond, and Silver City to complete the photos and video I’ll need. My plan this summer is to visit a mining area at least twice per month. Then, if I have a school team that wants to do that area, we’ll have much of what we need all ready to go for the 2010-2011 school year.

Ultimately, it’s the videos that this site is about. If you want to play them on YouTube, you can simply look up “davidvblack channel” in the YouTube search engine and all 23 of my videos (including the Business Profile Videos and my animation demo reel) are there. This blog’s purpose is to promote the videos and talk them up, giving some background into their creation. Once I have three topics done (the next topic after beryllium will be glass blowing), I will set up a dedicated website and upload the videos to iTunes, which will provide another location in addition to their existence here on this blog and on YouTube. There are some drawbacks to this blog as the primary source of the videos: since WordPress converts the video to FLV format, these videos won’t work on an iPod, iPhone, or iPad (I went to the local Mac store recently and tried out an iPad. The videos, being Flash based, won’t play). So I need a site like iTunes that can work for the Apple crowd as well (my kind of people).

Here are some stats on how the videos are doing: The episodes that have been finished so far have been the two parts of the Periodic Table featuring my interview with Dr. Eric Scerri of UCLA and the first half of the episode on beryllium.  On this blog site, the periodic table videos have been played over 370 times, and on YouTube they have been played over 1100 times. This isn’t to say that they have been played all the way through; the average play is about three minutes (which is why I try to keep my Business Profile Videos to three minutes or less).  They were uploaded about two months ago, so they’ve seen about 1500 plays or about 4500 minutes of viewing so far. I’m pleased with that. The beryllium video (which covers the uses, sources, and geology) has been viewed 82 times here and 27 times on YouTube since it was posted about two weeks ago. Considering it is a more limited topic, I feel that is a good start as well.

Even more surprising, to me, is that the Periodic Table videos have been close-captioned into Portuguese by Luis Brudna and have been viewed over 2200 times – twice as much as they have been viewed in English. Here is the link to the Portuguese versions: http://www.youtube.com/tabelaperiodicaorg#p/u/3/5lV6BIkAhvQ for the first of the four parts or http://www.youtube.com/tabelaperiodicaorg#g/u for the YouTube channel. The Beryllium Part 1 video has been translated on Vimeo at: http://vimeo.com/11555398. You can visit Dr. Brudna’s website at: http://www.tabelaperiodica.org.

Now it might seem that I’m just into an ego trip, obsessing over these stats, seeing who is referring to this blog from their site, who is putting links to these videos on their sites, etc. It’s like typing your name into a Google search to see if you really exist (I don’t show up until something like Page 19 of the search results . . . there are a lot of other David Blacks out there). But I do have a reason for tracking how this blog and the videos are doing: I hope to be able to show the reach of this project to potential funding sources. Since NSF turned me down this year, I’ll have to go begging hat in hand from other sources, and being able to show how many people are finding and using this blog and viewing the videos will be essential for a successful pitch.

If any of you out there read this, I would appreciate your writing a comment on how you’ve found this blog, what needs (if any) it has met for you, how you’re using it, etc. Any information I can get on how effective this blog is which goes beyond the bare numbers will be very useful for me. Meanwhile, I’ve been very busy with some client videos that were on a tight deadline, but I have a lull now for a few days and I’m getting back to Part 2 of the beryllium episode (this section on the history of mining, refining, and hazards). I’ll get it posted within the next week or two, give or take the weather (I’m also trying to plant a vegetable garden, if the ground will ever dry out enough). Then I’ll start on the blown glass video, which already has the narration and much of the video editing complete from my students last year. I’ve gathered more photos and need to add them. It will be done in two parts as well: one on the history and process of blowing glass, the other on the science and hazards of glass blowing. I’m shooting for mid-June to have those done, and will set up the iTunes site then. That should be enough episodes complete to start pounding the pavement looking for funding.

   Time is rushing forward and we are almost to the end of another school year at Mountainland Applied Technology College. Students in my Multimedia classes have been working daily to complete the alpha or “Director’s Cut” versions of their group video projects.

   Altogether, four projects will be completed within the next three weeks. These include projects titled: The Art and Science of Blown Glass (that group is currently creating their B-roll titles, images, and animations); The Art and Science of Stained Glass (this group is doing rough edit); High Pressure Alchemy: The Story of Synthetic Diamond (this group is capturing and editing the narrations); and The History of the Tintic Mining District (currently being captured and transcribed).

Eureka, Utah c. 1925

Eureka, Utah c. 1925

   This last project came about rather unexpectedly; the Tintic District is centered around the town of Eureka, Utah and was one of the richest mining areas in the West in the late 1800s. By 1960, the mines had closed and the town has since fallen on hard times. It is now designated as an EPA Superfund Site, and millions have been spent to cover up old tailings piles and replace contaminated soil.

   We had a team of students last year that filmed the area, but we didn’t have a good Subject Matter Expert that could tell the story. After driving through the town in early April, I saw that many of the historic buildings downtown are literally falling down and that this story needs to be told now rather than waiting for funding (my biggest challenge, besides having a full-time teaching job, is that I have no sponsorship as yet to support this project). I had one group of students that was going to do a project on pottery, but we hadn’t located a good site to visit. So I contacted June McNulty, who runs the Tintic Mining Museum in Eureka and arranged for him to be interviewed and to show us through the museum (which is only open by appointment) in an effort to preserve the history of this area before the reclamation efforts change things forever.

   On April 21 we took this team of students to Eureka and interviewed June and filmed the contents of the museum. Now I am going to be working on a final synthesis of two year’s worth of footage into two or more podcast episodes – one will tell the history of the mines, the other the history of the town and what life was/is like there, and perhaps a third will talk about the recent clean-up efforts and their impact on the town.

   The four projects will be completed by students and myself to an alpha test level by May 21, when we will have students from other classes at MATC watch the episodes and make comments and suggestions. At that point we will be too close to the end of the year for the students to do much more editing, so I will probably work on them over the summer to tighten the presentation/story and polish the images and audio.

   It will be a challenge getting this all done over the summer, since I will be in Philadelphia for three months researching background information and collecting images and photos on the history of chemistry in general at the Chemical Heritage Foundation, where I have been selected as a 2008-09 Fellow, sponsored by the Societe de Chimie Industrielle (American Section). This effort at CHF will result in at least two episodes as well, in addition to the four episodes this year and two from last year that I will be doing final edits on. My goal is to have 8-10 episodes completed and posted to this site and to iTunes and YouTube by the end of August. So far I have completed one episode on the rationale for this project. I will post that episode before leaving for Philadelphia (May 28) so that we can at least have a presence on iTunes and YouTube over the summer. I have been waiting until May 22 when I will be teaching the students how to compress and add metadata to podcasts; I’ll demonstrate how with this episode and take it all the way through posting and uploading to iTunes.

   Later today or tomorrow I will be adding a new post on how you, as an individual interested in this topic, can conduct similar research in your own community, or how you can participate to evaluate episodes or to provide sponsorship for this project.
