the last time it erupted was this year some time
Devils Tower formed from an ancient volcanic intrusion that cooled and solidified underground. Overlying sedimentary rocks have eroded away, exposing the tower-shaped rock formation we see today. The unique columnar structure of Devils Tower is a result of how the magma contracted as it cooled, creating vertical cracks and columns.
A volcano that has erupted within historic time is an Active Volcano.
The Newberry Volcano last erupted around 1,300 years ago, in the 8th century.
Devils Tower is a volcanic intrusion that is made of harder and more erosion-resistant rock than the surrounding sedimentary rock layers. Over time, erosion removed the softer sedimentary rock layers, leaving the Devils Tower standing higher than the surrounding area.
