London Mill
The 1880s London Mill was built to process gold ore from several mines on London Mountain. The first aerial tramway in Colorado transported ore down to the mill. Wooden tram towers are still visible on the mountain behind the mill. This impressive structure is now eligible for listing on the National Register of Historic Places, about five miles west of Alma on Mosquito Pass Road.
