I had one #4 camalot and my buddy had a second. Neither of use had any experience on wider cracks, but we both remembered reading something about "walking cams." We managed to convince ourselves that we could get a few #3s in then walk the #4s the last 1/4 of the route. Twenty feet up the #3s were tipped out, so I started walking the cams. Things were going well I got pink tricam in and maybe another small piece. The climbing up and down was getting old, but it was working. Then the #4s tipped out...
I made it to the top without incident, a week later a buddy proved the name apt. Offwidth technique is not a must, but it would probably make things easier.
Location
Screamer crack is located about 100 feet right of Super crack and about 100 feet left of the chimney (Mommas Squeeze box).
