The Periodic Intermittent Spring is located 5 miles east of Afton. The Spring is a cold water geyser with a flow cycle that stops and then starts up again from late summer through the winter. The water flows out of a ledge and cascades down the hill to Swift Creek. The flow stops and then after 12 to 18 minutes, it starts to flow again. This spring is the largest of the three intermittent springs in the world! You can visit the spring when it's performing by hiking a short trail that takes you along Swift Creek.

"The Sinks" is known as a river that mysteriously disappears. It's located just outside of Lander. The Popo Agie River flows out of the Wind River Mountains, curves into a cave, and goes underground and disappears. Further down, the river re-emerges in a pool called "The Rise." More water flows at The Rise than was originally in the Sinks which is another unexplained phenomenon. Sinks Canyon State Park is one of the best places for camping and hiking in the Cowboy State.

Devils Tower is located in Crook County near Hulett and Sundance with several origin stories. Many scientists believe it to be the core of a former volcano, caused by the cooling of lava deposits. Local native tribes share stories of how the rock erupted from the Earth, thanks to the Great Spirit saving children from an angry bear, who then clawed out the sides. No matter how Devils Tower / Bears Den was formed, it's one of the most remarkable wonders in the state.

6. Crack In Bighorn Mountains

Here is a rather recent development as far as natural phenomena goes. A large crack has opened up in the foothills of the Bighorn Mountains. The crack, which appeared over a span of two weeks, is many stories deep in areas. There is no explanation for the opening up of the earth in this area.

7. Unexplained Noises In The Sky

This phenomenon comes from the sky instead of the ground. People have reportedly heard siren like noises coming from the skies over Cheyenne and Laramie. There is no explanation for these strange noises either.
