Class B First-hand BFRO #8226

Campers hear late night screams near Arnold

7 August 2003 9pm Arnold, Calaveras County, California 2 witnesses

Account

The witness and a friend were stationary outdoors at night when they heard three loud, powerful screams from uphill in dense, rugged terrain. The first scream was estimated about 50 yards away, with subsequent screams sounding progressively farther at about 100 and 200 yards and minutes apart. The witness described the sound as human-like but guttural with bass, offensive or warning in character, and unlike known wildlife. After looking around and firing rocks with a slingshot, they heard the final, more distant scream.
