The camera traps caught a parade of interesting wildlife on film.
It is estimated that only 4,000 to 6,500 snow leopards are left in the wild.
A rare mountain weasel, also called an Altai weasel, peeks at the camera. The mammals prefer high altitudes, and the largest grow to about 11 inches (28 centimeters) in length.
