Campers hear late night scream near Mammoth Lakes

3 May 2001 about 1:00 am Mammoth Lakes CA, Mono County, California 2 witnesses

Account

The witness and a companion were at a cabin late at night preparing a truck for departure when they heard three very loud, long screams that started very close and then sounded progressively farther away. They checked the area with headlights, saw nothing, noticed lights from another cabin in the distance, and then secured themselves inside for the night. The witness felt the sound was threatening and unlike familiar animal sounds, but retained doubt about a natural explanation.
