Basins of Silver-Softbound

by Eric Twitty

The story of the Las Animas Mining District began with the Colorado Gold Rush of 1860, but it was silver that kept the local mines operating for over one hundred years. The region laid claim to many mining firsts in Colorado and the San Juan Mountains, and served as the cradle for engineering and mining practices that revolutionized the entire mining industry. The area was the scene of the first two mineral rushes to the San Juan Mountains, which included the first hard rock mine and ore treatment mill. The first and the longest aerial tramways were built here, which helped to further the inaugural practices of mining low grade ore. One of the first and most advanced mining power grids and power plants were used in the district. These practices ultimately helped save the Colorado mining industry when the bottom fell out of the price of silver.

About this book

Basins of Silver, softbound, covers the Las Animas Mining District in the San Juan Mountains of Colorado. By its description, the district's mines began with the 1860 Colorado Gold Rush but depended on silver for more than a century of work.

The description says the district was home to many firsts for Colorado and the San Juans. Two early mineral rushes passed through it, and it had the first hard rock mine and ore treatment mill in the range. Builders put up the first aerial tramway and the longest one there, a step toward working low grade ore. Its power plants and grid were among the earliest and most advanced for mining.

The description finishes with a claim about what that machinery meant: when silver prices collapsed, these methods helped save Colorado mining. The publisher's old product page for the softbound edition names Eric Twitty as the author and says he is an owner of Mountain States Historical in Boulder, Colorado, who has documented and assessed the historic mines of the Las Animas District for many years. Our record has no year or page count for this softbound listing, so we state none. The library also carries a hardbound edition of the same book, and our separate page for it has more on the district and the book.

Ways to use this book

Seeing the mill and mine ruins

Plan a trip around the historical society's season, then add Animas Forks on a summer day. The BLM page says the road from Silverton is passable in summer by two wheel drive, but beyond the town it may need four wheel drive.

Choosing between the two editions

This softbound page and the hardbound listing carry the same description. Compare the prices shown on each library page and choose the binding that suits how you will use it, on a trail or on a shelf.
