Washington Column has numerous rock climbing routes.[4] The first climbing ascent of Washington Column was made in 1935 by Morgan Harris, Dick Leonard, and Jack Riegelhuth, via a route they called the Piton Traverse. Climbing historian Steve Roper later wrote that the precise line of the original route was no longer known.[6]
