Yes, there is an area in Wyoming I will not camp in now ever again.
Out doing spotlight counts on black footed ferrets. Saw a strange light low in the sky , looked like a flame going up and down above a ridge then down to the ground. Guy nearest to it, about 1/4 mile away couldn't tell what it was. Head guy on the project could see it too and us about 5 miles away.
Boss called an end to the spotlighting that night.
Got back to town and my good friend was hiking in the Snowies and she and a friend saw the strangest lights coming up from behind a ridge miles away then it would go down and come back up.
The area is known for sightings.
