Spring Mountain Spring Moon
Gabe and I had an adventure yesterday. We went to the Agro Mine Tour, ate lunch at Beau Jo’s Pizza in Idaho Springs and finished off the day with a soporific soak at the Indian Hot Springs, also in Idaho Springs.
The mine tour itself is a cheesy, tourist-trappy thing with a clunky video, corny presentations and a self-guided tour after that. Still, the Double Eagle Mine, Gage is at its face (end) in this photo is remarkable in that it was dug by hand, by two men over the course of one year. About three hundred feet long, maybe five and a half feet tall and about 4 feet or so in width, it’s a monument to persistence, if nothing else.
The rest of the tour focuses not on a mine, but on the Agro mill, which in its prime, produced $100,000,000 worth of gold when gold was at $18-35 an ounce. It was fed by the Agro tunnel, a 4.5 mile tunnel dug through solid rock to remove waste water from various mines and to create a small railroad to deliver ore buckets to the Agro mill.
The Agro mill closed in 1943 when, on the last blast of the day, four unlucky miners 
dynamited a wall holding back water filling up an abandoned silver mine. The resulting flood geysered water from the tunnel for 9 hours. In addition to killing the miners the flood weakened walls and caused cave-ins along the tunnels length making the railroad tracks no longer usable.
The mill itself went down in stairstep like levels since most of the work proceeded through the aid of gravity. The Agro tunnel fed ore in from the top of the mill and the processing went in stages toward the bottom. A structure made of wood it looked like an unsafe place to have worked.
Idaho Springs is about 30 minutes outside of Denver to the west and well into the mountains. The Colorado Mineral Belt, which begins in the San Juan Mountains in the far southern part of the state, makes an arc up through Leadville and finds its terminus just a bit further north from Idaho Springs. Along this arc lie most of the mines in Colorado, many of them producing, like the mines the Agro Mill serviced gold, silver, copper, lead and zinc. Some have molybdenum and other metals. There’s a big, working molybdenum mine outside of Leadville.
Idaho Springs is a tourist town, primarily, located on either side of a long main street paralleling I-70. It has some residential housing, but not much. Service stations, inexpensive motels, restaurants, curio shops, a knife shop, a hardware store which sells gold panning supplies, that sort of thing.
And the Indian Hot Springs. The facilities, both the main building and the adjoining motel, saw their better days many years ago. The springs, though, deliver. Gabe and I swam in a large pool of water, 100 degrees +. There are, too, hot springs caves, a men’s and a women’s cave where clothing is optional. Kids under 16 are not allowed in the caves.
After all that, it was back to Denver and a quick exit so Grandpop could beat the rush hour traffic on the way home.
