Cave and Adit Surveys 



One cave and several mines were located and surveyed for evidence 



of bat use on the Deerlodge National Forest in 1992. These were: 



The Crater NW 1/4 Sec 10 T8N RllW 



This cave was visited twice in 1991. No evidence of bat use 

 was found at that time, though a Silver-haired bat was 

 captured in a mist net leaving the cave in September 1991. 

 The cave was once again searched for evidence of use in 

 1992. None was found. The harp trap was again placed in 

 the entrance. No bats were captured. 



No other caves were located or surveyed on the Deerlodge National 

 Forest in 1992. 



The Mountain Lion Mine 



This mine adit, located east of Princeton, has been gated to 

 allow passage of bats. Mist nets were placed near the 

 entrance on the evening of August 19, and a bat detector was 

 used to listen for activity, but none was heard leaving the 

 mine, though Big brown bats were heard in the vicinity. No 

 bats were captured.
