Did you know Devils Tower was tho first national monument? Teddy Roosevelt named it such in 1906. We took a beautiful 1.3 mile hike around the base of the Tower. It was amazing and the pix don’t do it justice. There is debate over how it formed but most say it was formed by igneous rock underground. The sedimentary rock around it eroded away and here it stands. It used to be taller than its 1200 feet as evidenced by all the rocks at the base. Here endeth the geology lesson.

On the road to our campsite. Saw some prairie dogs and more cattle. Hope to see mount Rushmore lit up tonight.
