A geologic map primarily displays the types of rocks and their distribution within a given area. This type of map provides essential information about the geological formations, including different rock types, their ages, and structural features such as faults and folds. The color coding and symbols used on the map indicate various geological formations, allowing geologists and researchers to analyze the subsurface geology effectively and understand the history of the area.

While elevation, water sources, and infrastructure such as roads and trails can be important aspects to consider in broader geological or topographical studies, they are not the primary focus of a geologic map. These aspects may be represented to some extent for context but do not define the principal function of the map, which is specifically oriented towards displaying geological features related to rock types and structures.
