An event every year that begins at 12:00 am on day 24 of September, repeating indefinitely

On September 24, 1906, Devil’s Tower in Wyoming was established as a national monument. An eye-catching geologic protrusion near the Black Hills, its formation dates back to the Triassic Period, 225-195 million years ago (!) ⛰⛰⛰

The monument is considered sacred by local Native American tribes, who have passed down its legends from generation to generation.

Did you know? Thanks to its striking appearance, Devil’s Tower was famously featured in the 1977 alien movie, Close Encounters of the Third Kind. 👽🛸
