Not for lack of trying, though.
Popular books and scientific monographs have been written, supposed foot- and handprint casts scrutinized by experts in critters' dermal ridges, hair samples studied with microscopic intensity, a single 55-second film given Zapruder-like, frame-by-frame analysis.
Don't hold your breath for a big reveal any time soon. Heck, cryptozoologists can't even get to the bottom of Loch Ness Monster phenomena, and that's focused in a single lake in the Scottish highlands. Bigfoot - a.k.a. Sasquatch, or its quasi-scientific name, Gigantopithecus - could be anywhere from here in the Shasta-Trinity National Forest to Oregon, Washington or British Columbia.
It's better just to let the mystery be, don't you think? Let people believe what they want and keep a torch for the apelike creature with size-15 feet and God-awful primordial stench. Who are we to say they're wrong, deluded or absolutely bonkers to think the big lug could still be roaming these very woods?
