This is the leftmost of two short cracks that can be found on the north aspect of the boulder pile surrounding Headstone Rock. They are both worthwhile short trad climbs, and are shady on a sunny day. Both sides of the crack are lined with grippy pinches and edges. About the same difficulty as Headstone Crack Right.
Leaving Ryan Campground, walk east toward Headstone Rock (which you can't possible miss). When you reach the base of the formation, walk around to the left (north side) until you see these two obvious short cracks.
