Remember this from the 1977 “Close Encounters” movie?
The Devils Tower is a sacred site to Native Americans and is an NPS National
Monument. Located in the Black Hills of northeastern Wyoming, this remarkable geologic butte stands nearly 900 feet tall from it base to the top. The rock is igneous and was formed when the molten lava intruded into layers of sedimentary rocks. Those rocks weathered away, leaving the Devils Tower that we see today.
There is interesting history of both the geology of the tower, as well as the history of human involvement of the site. This was the first National Monument, so designated ten years before the National Park Service was founded. Study the Devils Tower website for details about the park, its history and current covid restrictions.
We visited Devils Tower back in 2015.
