Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region. The San Juan and Uncompahgre National Forests cover a large portion of the San Juan Mountains

Splitting of the Atom - apparatus used by Dr J D Cockcroft

Dr John D Cockcroft listening for sounds indicating atomic disintegration brought about by the bombardment with high-velocity protons of the lithium nucleus, which appears to break up into two helium nuclei. Physicists Cockcroft and E Ts Walton developed the Cockcroft-Walton accelerator to artificially accelerate atomic particles to high energies, to enable them to observe the results of splitting the atom. At the Cavendish Laboratory, Cambridge.
