When: In the early 1980s Where: southeast of Gillette, Wyoming Who: Woman who was in her late 20s when this occurred. What: While working in sagebrush covered land, our crew walked up to a slightly sunken area where there were several trees. With few trees nearby, the shade from them was welcome with the summer heat. We sat down on the ground and were drinking water, taking a break. The area was only about 200 – 300 feet in diameter. I got up to walk around and felt an odd physical essence about the spot. It was like there was a coolness/dampness/something compelling about the area that I could not put my finger on as to what it was that made me feel drawn to it. It was not the shade, not the trees. It wasn’t a scenic but was a rather plain spot. What attracted me was that I felt there was something beneath the ground there. The Black Hills of South Dakota is several hours east of that area, and I know the Black Hills has caverns. However, I am not aware of any caverns in eastern Wyoming. We then went back to work, and it was with reluctance I left the spot — I sensed the sunken spot held a secret, within the earth that lay below it. – Anonymous
