Isosceles Area

These are three blocks of rock which are found about a third of the way up the trail from Highway 50, where the trail from Sugarbun comes up to meet the main trail. All of the routes are designed for and to be kept as toprope problems.

South Rock: #1 is 5-12+, anchors not in at top; can tie off to tree behind for now. #2 is a more-difficult-than-it-looks crack at 10b. #3 is 10a/b. #4 is 5-8.

East Rock, northeast face, is 50 meters to the northeast of South Rock: #5 is a 10b corner, unfortunately divided by a ledge halfway up; #6 is a steep 5-11 face route; as are #'s 7 & 8; #9 climbs a corner, then moves up & right onto face climbing, just left of a small ledge.

East Rock, southeast area: #10 is a set of convergent cracks; A is a hard variation that climbs the pillar; B is the right crack at 9 or 10a; C is the left crack at 9 or 10a; done together, the crack system is 5-9. #11 is 10b, a knobby face route. #12 is a major crack; A is the easier direct start at 5-6; C is the difficult lieback start; B is pure stemming at about 5-9. #13 is a 10b knobby face route. #14 is a pure stem with interesting exit move at top, at 5-8. #15 is 5-8 at the start and quickly eases. The bolt/hanger is used as a directional.

East Rock, southwest face: #16 is 5-7 at start and quickly eases; #17 is a 5-11 corner/face.

North Rock, northeast section, the three routes all climb to the top of the block to start: #18 steps back into the chimney, then ascends steeply at 9 or 10a, and up to the right of a blocky protrusion; #19 ascends the dihedral onto the sloping ledge, then up steeply via a vague gully/corner; #20 steps out left and up, finishing up through a gully/crack.

North Rock, middle section: #21 is 12 or 13 on a steep face with small features; #22 is the prominent crack at 10b.

North Rock, west section: #23 is a 12 or 13 face; #24 is a 5-8 jam crack - start on the outside of the bottom pillar; #25 is a 12 or 13 lieback problem in a bottoming crack.
