Class B First-hand BFRO #3072

BFRO Investigators detail activity around Twain Harte

March 2001 Twain Harte, Tuolumne County, California

Account

Investigators found fresh broken trees, dozens of footprints and two nests where a trail crossed a road and staked out the spot. No creature was seen, but something large moving on two feet approached the stakeout before fleeing downhill through brush when a car passed. The sign was documented the next day with footprint and tree-break measurements and a body-length impression in one nest.
