Begin by doing a couple of face moves to get to a seam that angles up and right. It intersects a more vertical finger crack that makes up the meat of the climbing. Gear is really sparse through the bottom 15 or 20 feet, you could deck if you blow it. The crux is at about 15 feet, using the crack and a few key feet and crimpers to get to a decent finger lock. After this, the climb eases up and is 5.9 or 5.10 fingers.
North side of Cranner. In the alcove containing U238, but across on the other side.
Finger sized gear. Two bolt anchor at the top. You can climb a 3rd class ramp left of this route to set up a top rope.
