to the large number of cracks and fissures associated with the 

 canyon walls. Most of the possible roosting sites are a 

 considerable distance up the canyon walls and are not accessible 

 for searches. Few bats were captured, possibly due to the 

 extensive area of the stream that is available to them. Bat 

 abundance in this area would probably be most effectively 

 determined using a bat detector. This site was netted once using 

 two 5.5 m nets on 19 June. The following bats were captured:

The Kelt Ponds (T. 9 S., R, 27 E. , Carbon Co., MT; elevation: 

 1524 m) , three in section 25, one in Section 24, are ephemeral, 

 and during the summer of 1989 were dry until 13 July. The 

 eastern most of the ponds in Section 25 was netted on one night, 

 11 August. No bats were captured, but 5-6 Myotis spp. were 

 observed foraging near the nets shortly after sunset. This site 

 is in the Utah juniper-blacksage ecosystem, and is located on BLM 

 land. 



Bent Spring (T. 8 5., R. 25 E. , Sec. 1, Carbon Co., MT; 

 elevation: 2285 m) is located on USES land and consists of a 2 m 

 diameter wooden cattle trough surrounded by open grassland. 

 Douglas-fir forest characterizes the area above the trough on a 

 ridge approximately 500 m uphill from the spring, and rocky 

 canyons are prevalent below. Only one bat was captured here, a 

 male Myotis evotis, on 3 July. Two 5.5 m nets were used. 



Listed below are several water sources identified during the 1989 

 field season that were not investigated extensively. Some of 

 these sites should be netted during subsequent field seasons. 



Harsten Flat Pond (T. 7 S., R 27 E., Sec. 29, Carbon Co., MT; 

 elevation: 2012 m) is located on land owned by the Schwend 

 family. This is a small pond in Montana grassland ecosystem on 

 Harsten Flat. I did not visit this site, but was infoirmed of its 

 existence by USFS employees. 



Kruger Pond (T. 8 S., R. 28 E., Sec. 7., Carbon Co., MT; 

 elevation: 2591 m) , approximately 70 m by 20 m in size, is 

 located on USFS land in Douglas-fir forest. One Myotis spp. was 

 observed at this site during a rain storm. This pond's proximity 

 to both Mystery Cave and Little Ice Cave suggests that it may be 

 an important foraging site for bats roosting in those caves. The 

 pond should be netted and assessed with a bat detector.
