Probably the most well known landmark in eastern Wyoming, Devil’s Tower is formed of columnar jointing and remains a subject of study. It is also the United States’ first national monument. The rock faces here are great for climbing, and they were out this morning. There are two trails around the tower, an inner and outer. We walked the inner to stay close enough to see the details. Although it’s all the same igneous rock, the sun seems to change colors and perspective from different sides. Really worth the stop!
