Class A First-hand BFRO #22434

Backpacker sighting off the PCT in the Marble Mountains Wilderness

3 August 1998 about 1 or 2 AM to 5 AM Etna, Siskiyou County, California 1 witness

Account

The witness was sleeping alone on a rock ledge above a drainage when she heard loud repetitive whooping and howling from far below. The source moved rapidly uphill, climbed a steep cliff to the ledge, and ran past her toward the peak above, pausing briefly to look toward her. It then vocalized from the top of the peak until near sunrise, and she left the area at first light.
