Mammoth Cave

Map of the Mammoth Cave: Accompanied with Notes - via Library of Congress

This is a remarkable map from 1835 (Doolittle & Munson, Cincinnati) showing the geographic view alongside diagrams of each section or "room". 

Different colors are used to differentiate the sections to help unify the section drawings with the map.

Here is the area under Mr. Gatewood's House, near the cave's mouth,

and the view from below.

The map includes a view of the mouth of the cave above the title block.

Here is the mouth on the map.
