On the far right side of the Mule Hollow wall in Big Cottonwood Canyon is the Jamcrack. Last weekend my buddy Dan gave me a call and asked if I wanted to go Bouldering. I said, "sure, ill bring a rope." Seven hours later Dan, Hayden and I had finished the 4 pitch route with the 1 long hour approach. It was a good outing and far from the original plan of staying only a few feet off the ground.
