Class B First-hand BFRO #18050

Series of loud vocalizations from two sources heard in the Yellowjacket Mountains

1 August 2000 about 10:00 pm Yellowjacket Mine- Challis, Lemhi County, Idaho 2 witnesses

Account

The witness and a relative camped at the end of a forest road and prepared to sleep in their tent. They heard loud hair-raising howl-like screams coming from opposite directions for several minutes, as if two sources were calling back and forth. Minutes after the sounds stopped, a foul rotting odor drifted through camp while the forest remained completely silent.
