18 August 2001 pre-dawn, 4:45AM to 6:30AM Arnold, Calaveras County, California 6 witnesses

Account

A group camping in the Sierra foothills was awakened before dawn by prolonged loud screaming vocalizations occurring in repeated series. The sounds began at 4:45 a.m. and continued for about 20 minutes, with additional shorter series afterward and again around 6:30 a.m. from a different direction. Six campers heard the sounds, which the reporter felt resembled reference recordings and were not known forest animal sounds.
