The tower is South Mesa Pinnacle. There are remnants of bolts leading from the ground into the crack you mean. Moving counterclockwise around to the other side, is the Dodger route; crack -> grotto -> formation-splitting crack, which at that height is an airy chimney.
Continuing counterclockwise, there's another line with a bolt visible; buttress -> crack -> roof leading right -> subsidiary summit, -> easy step across the scary chimney. That's "200000 Light Years from Home".
