Backpackers hear growls, knocking and observe two large, hairy bipeds at Surprise Lake

The witness and a companion were camped at Surprise Lake at dusk when they heard patterned knocks and rock-on-tree sounds. After the witness threw a rock against a tree and heard a similar sound returned, they saw a large brownish-red animal squatted and swaying behind a tree upslope. They attempted blurry photos while knocks were heard from behind the camp and from the animal's direction before leaving at first light.

A quick ask from the person behind the Anomadex: if you allow analytics, Google Analytics shows me which places, phenomena and searches you're most curious about. That tells me which regions and sources to add next and what to make easier to find. It never sees your name or anything you send me, and nothing is set unless you say yes. Privacy
