The monolith was mentioned in the journal of the explorers Lewis and Clark as their camping place on November 2, 1805.[2] The name is phallic in origin,[2] specifically, the column's original name was "Cock Rock". The Chinook word for the rock was iwash, referring to penis.[3] The name was later modified to Rooster Rock so as not to offend the public.[3]
The eastern portion of the park is designated as a clothing-optional beach, the first officially designated clothing-optional beach in the U.S.[4] The only other clothing-optional beach in the state, after Glassbar Island's closing, is Collins Beach, on Sauvie Island in the Columbia River, north of Portland.
The area around the parking lot has been a favorite astronomy spot for amateur astronomers in the area, with organizations such as OMSI hosting multiple star parties at the venue.[5]
