Access Issue: Rebolting Complete! Details

CA State Parks officially reopened Big Rock to public access April 28th, 2018. After months of effort 53 anchors and 232 bolts have been upgraded to 1/2" X 2.75" stainless steel Powers 5-piece bolts and rings.

Description

At the center of the larger portion of the Big Rock face, lies a water streak. The Trough runs straight up this, via nine bolts (ten, if you clip to intermediate anchor). Picnic tables for the area sit directly underneath. The crux comes after the first bolt, with the balance of the route having copious amounts of hand and feet holds, but are glassy smooth and water polished. Generous bolts protect this fun climb.

Protection

9 bolts (10, if clipping the intermediate anchor). Can be done in one long pitch with a 60 meter rope, or done in two if wanting the multi-pitch experience and practice. Bolted anchors are found midway, 3/4 the way, and at the very top just to the left.
