The Oregon Cavemen, claiming direct descent from Neanderthal man, incorporated as a unit in October 1922 during a secret ceremony in the depths of the Oregon Caves, their claimed homeland and a national monument. Comprised of local businessmen, they traveled widely to spread goodwill and tourist information, appearing at events of national and local interest including the opening of the Golden Gate Bridge, a Broadway show, and the Bay Area's Treasure Island Exposition. Dressed in animal skins with horsehair wigs, buck teeth, and big horns, they ran through parades and public gatherings, often bringing a rustic cage in which they imprisoned victims for public display. They were known for pranks and jokes on important visitors in Grants Pass and elsewhere, and for quickly capturing pretty girls who looked like they could take a joke. Their main purpose was to publicize Grants Pass and Josephine County. Their rituals included orienting members to the geographical and scenic features of the Caveman Domain and instructing them in Caveman tactics for greeting visitors, including presenting an inscribed chamois. Their governing body was kept within a small circle of officers including Chief Bighorn, Rising Buck, Wingfeather, and Keeper of the Wampum, along with a council of Eagle Eyes serving as a board of directors. Making their own rules as they went along, they aimed for the most fun and the best gag while spreading the good word for Grants Pass and Josephine County and urging people to visit the Rogue River Valley.
