Turtle Rock is just south of Sledgehammer. It is a very large rock, and has a 3rd Class slabs on the northern end of it. This is how you get to some of the routes such as Balding Bob Ain't So Bold, and Omega Crack. The other routes you access by walking around either side. I do not know the first ascents, so feel free to comment on who got them or any other corrections. I am just pulling this information from the old "Black Hills Needles: Selected Free Climbs" guide book. It is the blue one. I just thought it would be good to get these climbs out there as they are very fun! Enjoy.
