This is a stunning, massive boulder with a 15ft roof. Take the ridgeline across, heading away from the tunnel and Great American Roof. Eventually, to the downhill of the low cliffline, you will find the large Galaxy Boulder.
This boulder has no walk-off, so be sure to warm up on "Galaxy Warm-up/Down Climb" first and foremost as to be comfortable and confident on the V1 downclimb.
