Lewis and Clarke originally christened the large basalt monolith on the banks of the mighty Columbia River "Cock Rock", but prudish Oreganders thought well enough to change it. Thankfully today, modern beach combers have returned to their roots. "Rooster Rock" now finds itself home to one of the nicest nudest beaches on the West Coast.
This painting might help explain Lewis and Clark's obvious apparent fascination. After two years together trekking through the uncharted wilds of the United States I'm sure Lewis and Clark had probably seen enough of each others peckers to name a rock in commemoration of their memorable time together.
Rousing the randy rooster of Dan, who recommends everyone check out Portland's riverine nude beach. You know, just in case you forgot what a cock looks like.
Granted, there may not be much in the way of uncharted wilderness left to "discover" but sometimes the World Wide Web makes a river where none used to flow: fashion genius discovered by Colby on a random "Rooster Rock" Google image search. :-)
