Description

This excellent route begins behind a big tree on the brushy ledge that crosses the lower south side of the first tower on the Northeast Ridge. Hike the Solitude Lake Trail to Shelf Lake. Just before reaching the east end of Solitude Lake, hike talus to a high point on the shoulder of the Northeast Ridge. Climb the initial slab of Ripsaw for about 60 feet then break left around the crest, descend a short way and continue across a ledge system to a big tree.

P1. Climb the left side of a wedged flake then climb up the outside of a huge flake to a good ledge at its top (8, 90 feet).

P2. From the far left (west) end of the ledge, pull up and left into a shallow, left-facing dihedral (9 s) and clip a bolt. Follow the scalloped dihedral past 2 more bolts and a fixed pin to a left-leaning roof/dihedral. Lieback the dihedral and belay at its top beneath a second left-leaning roof/dihedral (10a, 90 feet).

P3. Climb the second roof/dihedral through an apex, stay left and belay at a horn in a crack that goes straight up the wall (10b, 70 feet).

P4. Follow the crack to the top of the wall where it veers right to join Ripsaw (9, 90 feet).

Rappel Ripsaw (2 X 100 feet) and down-climb the initial slab (class 4) or climb a short way higher to the top of the first pinnacle on the Northeast Ridge and continue with Ripsaw.

Location

Hike the Solitude Lake Trail to Shelf Lake. Just before reaching the east end of Solitude Lake, hike talus to a high point on the shoulder of the Northeast Ridge. Climb the initial slab of Ripsaw for about 60 feet then break left around the crest, descend a short way and continue across a ledge to a big tree.

This point can also be reached from Black Lake. Approach as for the South Face routes. Break right where the terrain seems to beckon then traverse a long way right across talus until it is obvious to scramble up a gully to the ledge with the big tree.

Protection

Full rack from thin to 3 inches. Pitch 2 has 3 bolts and a fixed pin, but this is no sport climb.

This LA piton lies between the second and third bolts on pitch two of Sidewinder.  A green Alien can be placed just below the pin. I set out to lead this pitch without any fixed gear and was turned back after making fairly committing moves into the scalloped dihedral.  The "crack" I had envisioned turned out to be a seam for most of its length.

[Hide Comment] It is hard to believe that no one has climbed and commented on this route. It is really good! Jan 27, 2018

[Hide Comment] Hi Richard,
It's actually on my list, for whatever that's worth. Question though, why did you give this zero stars in your new book? Typo? May 11, 2018

[Hide Comment] Approach from the Solitude Lake side, and cut a mile or two off of the Black Lake burden you might have been thinking about. It has great views, and the trail is actually not bad.

The Diamondback variation of P2 is a 2-star route. It could get more if it cleans up a little more, but the feet were scaling quite a bit, and the gear is sometimes poor or in poor rock. The first part of the climb is certainly a no-fall zone. Finishing up Ripsaw to the true summit is a good add-on.

P1. 5.7, 70'. This takes a large piece if you want it. Save a 3" for the belay.

P2/3. 5.10b/c S Diamondback variation seems most natural to link these 2 pitches. The feet are scaly, and the pro substandard at least on the first 1/2.

P4 is mostly 5.6/5.7 with a single move that might be 5.8/5.9 and climbs/protects quite well, actually.

Finishing on Ripsaw to the summit is a bit over a mile and mostly 5.7 or well below. Jul 14, 2018

[Hide Comment] See beta pick for pitch one on Diamond Back page. Great route, but I was happy to 2nd the crux as it was hard with bad gear. Jul 15, 2018
