Dave Bobbitt, left, geologist with the U.S. Forest Service, and Lauri Hanauska-Brown, Non-game Wildlife Management Bureau chief for Montana Fish, Wildlife & Parks, search the walls of Lick Creek Cave in the Helena-Lewis and Clark National Forest for bats they can test for   white-nose syndrome.  The syndrome is caused by a fungus, Pseudogymnoascus destructans, which has yet to be detected in Montana but has killed millions of bats in the eastern United States and Canada.
