This profile is composed of both the surface topography and the inferred geology underfoot.This map displays the large-scale (also called "regional") geologic features they have inferred are present beneath the landscape.Along with these geologic maps, we can reconstruct a regional geologic cross-section which would be like a great "geologic slice" through the landscape.We have seen that a cliff or a road cut is a local "geologic cross-section" -- a side view of the geology at one location.
As geologists piece together the information at various outcrops, they can begin to assemble a "geologic map" (like a road map) of an entire region (consisting of many square miles).Cliffs, road cuts, and non-vegetated landscapes allow us glimpses into geology which is often hidden from view.
