Class B First-hand BFRO #10260

Four climbers report repeated vocalizations

4 July 1978 between 12:00 AM and 1:00 AM Libby, Lincoln County, Montana 5 witnesses

Account

Five campers at a basecamp on Mt. Snowy late at night heard a long loud vocalization coming from a ridge behind camp. The sound began like a low growl and rose to a high howling scream, repeating several times over an extended period while seeming to move farther away. The men, experienced in the woods, said it did not match known animals, and a search the next morning found no sign.
