Geologist and mining engineer Greg Graham works to unlock a bat gate at the entrance to the abandoned 'Falling Man' gold mine. The gate is designed to allow bats to fly in and out of the mine interior while keeping human visitors and other large animals excluded. Greg is opening the gate for a bat survey by biologists.
