Lewis Mill
San Miguel County
The 1910 Lewis Mill is a distinctive example of engineering and high country milling technology. At the time of its construction, the Lewis Mill was a state-of-the-art ore concentration mill. The Lewis Mill is the only transitional mill in Colorado that retains its original milling equipment.

Additionally, the mill utilized technology developed by Robert H. Richards, a nationally recognized mining engineer from the Massachusetts School of Technology. The Lewis Mill contains the only remaining example of the Richards method of ore concentration in Colorado and is listed at the State level of significance.
