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, at the urging of Dalles businessperson Victor Trevitt,^[4] 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.^[5] 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.^[6]
