The summer of 1941 saw the American Museum in possession of a permit to excavate two caves on the Crow Indian Reservation in south-central Montana. Those caves were selected from other possibilities the year before by my colleague, Junius Bird; but, owing to his absence, the permit, originally issued to him, was changed in my favor. August and September were chosen as the most favorable time, and five weeks were devoted to actual field operations.
