A number of active fault underlie Lake Clark National Park and Preserve's rugged terrain. The longest, at 225 km, is the Lake Clark Fault which lies between the Alaska Range and the Chigmit Mountains, under the lake itself and Lake Clark Pass. To the east are the Telaquana and Mulchatna faults.

Antlers are covered with velvet while still growing - the velvet contains blood vessels that bring nutrients to the growing tissue.

Female caribou have antlers, but female moose do not. Male moose and all caribou shed their antlers in the late fall or early winter, and grow new antlers in the spring. Caribou and moose are the only two members of the deer family found in Lake Clark National Park and Preserve.
