bat research

Geologist and mining engineer Greg Graham squeezes through the bat gate of the abandoned Smoking Dump gold mine. The gate is designed to allow bats access to the spaces where they hibernate and roost in the mine interior while keeping human visitors and other large animals excluded. Greg is going to inspect the mine in preparation for a bat survey by biologists. Coleville National Forest, Washington.
