April, 19 16] Reames Cave 211 



The drainage is into the Mad River valley and is mostly 

 surface run-off except in the vicinity of Mount Tabor, near 

 both ends of which and to the southward are depressions. There 

 is no doubt that some of these are sinks. Some, however, 

 may be kettle holes associated with the near presence of the 

 broad moraine. The abrupt ending of some small streams 

 in ponds near Mount Tabor, shows that there is underground 

 drainage in its immediate vicinity. 



Geologically, the cave is located in the Columbus limestone, 

 a small outlier of which forms Mount Tabor. This is a small 

 edition of a similar situation in the double pointed hill near 

 Bellefontaine. 



Several small quarries have been opened near the base of the 

 Mount, for local use. In a specimen from one of these Miss 

 Rose Gormley identified the following fauna: Atrypa reti- 

 cularis, Atrypa spinosa (?), Cyrtina hamiltonensis, Leptcena 

 rhomboidalis, Rhipidomella vanuxemi, Spirifer divaricatus (?), 

 Stropheodonta hemispherica, Zaphrentis cornicula (?), Dal- 

 manites calypso. 



This fauna, together with the lithologic character of the 

 limestone, and the fact that at the cave entrance is exposed 

 fifteen feet of Ohio shale immediately above the limestone, 

 leaves no doubt as to its age. The Ohio shale at the entrance 

 is the only known occurrence of it on the hill. It seems to 

 have been protected from ice erosion, because it occupied the 

 bottom of a shallow sink, which subsequently enlarged and 

 deepened to form the present cave entrance. 



Glacial drift covers the southern end of Mount Tabor in a 

 train that stretches out from the limestone core. The northern 

 end of this core was left exposed by the ice. It has the steep 

 slope to the north and the drift to the lee characteristic of ice 

 shaped hills. 



Reames Cave is approximately 1800 feet long. Its general 

 form is that of the letter F, the entrance being at the base of the 

 letter and the fork 1100 feet from it. The passages run in a 

 northeast direction up to the fork, where one continues along the 

 same line and the other branches off to the north. (See map). 



The width of the accessible galleries varies considerably. 

 The maximum is fifty feet. Where this wide the height of 

 all but a small passage may be reduced from a maximum of 

 twenty-five feet to three feet or less. The wider places are
