Daylight Sighting by Hikers Near Bennett Mountain

July 1986 Afternoon, between noon and 2 pm Santa Rosa, Sonoma County, California 3 witnesses

Account

The witness and two companions were hiking toward Bennett Peak and stopped to rest before a large climb. They heard loud snapping and cracking of limbs across a valley and saw a large hairy back moving very fast uphill through brush, clearing foliage out of its way. Afterward they visited the spot and found broken branches several feet above the ground.
