Mouth pops heard by Mountain Lion hunter near Custer State Park

The witness was concealed while hunting mountain lion and using a distressed-fawn predator call. From behind, the witness heard repeated knock-like or mouth-pop sounds from two directions, followed by deep mumbling described as an unfamiliar language. The witness saw nothing, moved into the open, then quickly hiked out and has not returned to the area.

Possible stalking outside a campers' tent in the White Knob mountains

On the last night of a camping trip, the witness lay awake in a tent around midnight and heard close footsteps and deep breathing from a large presence outside. The witness sat up, armed, and turned on a flashlight, after which all sounds stopped and a sudden intense dread lifted. No animal was seen, no odor was noticed, and nothing further happened that night.

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
