Today wraps up the exploration of the Cave of the Mounds with an image of the exit area just before ascending from the cave.
This image shows the extent of modifications made to the cave for safe tourist access. Not only are there permanent concrete stairs and handrails, but the image shows a larger floor area that is likely also poured concrete over the cave floor. In other pictures there is a visible wooden floor, which may have been cheaper or simply more practical given the conditions of the floor in that part of the cave.
The description states:
Exit Hall — North Cave, Blue Mounds, Wisconsin
The photo is part of a larger series which dates from the 1940s.
