Campers have frightening experience in the Marble Mountains Wilderness

Account

In summer 1977 the witness and a companion were backpacking and camped at a trail junction near a creek in forested mountain country. In the middle of the night they were awakened by loud crashing of logs and rocks being hurled in the streambed below. Bipedal footsteps then approached up the slope to behind nearby trees, with heavy breathing heard high in the air and a humph sound after the witness shouted, before the creature walked away parallel to the creek.
