Book Description
Excerpt from Geology of the Columbus Quadrangle These disintegrating processes are at work not only in the rocks which are actually at the surface, but also in those at some distance below, for the loose outer portion of the surface material is penetrated by the atmosphere while ground water may carry the active chemical agents to a considerable depth and there work changes similar to those which take place at the surface.
