The National Park Service called Split Butte one of the most unique features of the Snake River Plain. [3]: 8
The name of the crater comes from gap in the upper tephra layers at the eastern side of the butte. [4]
Split Butte is also a maars and a tuff cone. [5] At one point it had a lava lake. [1]
The split, which is located on the east side is believed to be caused by wind erosion. The winds have also caused more pyroclastic debris to the east side. [4]
