The test piece boulder problem for the Marquette area. It was done in the early 90's by Mike Moss at maybe V4, but a key hold had broken and it took another 4 years for Josh to piece it together. Start far right on your bum. With your hands on the lip of the overhang, drop below the lip and traverse 20 ft to your left till the overhang comes to an end and top out. Good luck.
Before reaching the black rocks jumping area, there will be a big dirt parking are on your right. Park here and take the trail over or around the mound at the back of the parking area and down to the lake. Walk straight out on the rocks till you'd have to jump in, then turn to your left to find a nice secluded overhanging area.
