Reames Cave is one of the largest if not the largest in Ohio. 

 It owes its size to the extent of its narrow chambers, rather 

 than to their width or height. These chambers are all on one 

 level or nearly so. The floor at the entrance is thirty feet 

 below the ground surface. It descends gradually to the north- 

 eastward, but so gradually that at the extreme end of the cave

a descent sixty-five feet below the surface is unnoticed. Most 

 of this descent is along the eastern arm of the Y. 



At the extreme end of both branches the floor of the cave 

 is quite muddy, due to the constant dripping from the roof, at 

 least in part. This is due to the fact that the cave in its north- 

 easterly course passes beyond the Hmit of the Mount Tabor 

 hill and is partly under the valley to the east of it. While the 

 surface drainage into this valley from Moimt Tabor carries 

 off most of the water, enough descends through the mantle 

 rock to give an abundant supply for solution and deposition 

 in the cave.
