Entrance to "Long Route", No. 16 from the series "Mammoth Cave Views"

Text printed on reverse of stereocard: ENTRANCE TO "LONG ROUTE." Is on the left of "Giant's Coffin" and so narrow and low that visitors have to stoop almost to the ground in passing through it. On the right may be seen the end of "Giant's Coffin." By some it is supposed that the water receded from the main cave through this passage.
