Temporary closure during construction. Do not climb at Riverside until formally re-opened or future access will be jeopardized.
One of the finest crack lines at the Riverside Quarry, this is located on the slightly overhung face around and left from Hump or Dump.
Climb the vertical thin/hand crack as it arches up and left and gets slowly wider and steeper, the crux towards the end as you either jam wide fists near the lip or struggle to get smaller, better jams deeper inside the crack which flares; handrailing the lip is another option if you have the juice.
A local classic that would see much more traffic if in another locale.
