How large are bigfoot's feet?

The trap was built in 1974 by the North American Wildlife Research Team (NAWRT), a no-longer-extant organization based in Eugene, Oregon, that was inspired by Perry Lovell, a miner who lived near the Applegate River, who found 18-inch-long human-like tracks in his garden. NAWRT operated the trap, keeping it baited with carcasses for six years, but they only caught bears.
