Devil’s Washtub (also “Sloshing Whatnot”) is a wonderful example of a Blowhole within the Copper Harbor Conglomerate. With strong waves the spot is very exciting! In calmer moments it can be a spot for swimming and one may pass through a lake arch of conglomerate, or the arch may be filled with loose gravel.

Parking is very limited and the site is unmarked, but is opposite the Dapple Gray B&B, where M26 turns south away from the shore about 2 mi west of Copper Harbor.
