This is a short route on the North face (containing at least 5 routes) of Triangle Rock. It lies just uphill & left of Stud Pile. Although it can be led, a TR might prove more palatable. It is not a destination climb but worth a run if you are already at Triangle Rock.
Approach this as for the East side of Twin Owls & Gollum's Arch. Approach as for Gollum's Arch, head down a gully, then traverse to the crag. This rock lies East of Twin Owls & is down & East of Gollum's Arch. Expect a bit of bush.
On the North face of Triangle Rock there is a series of 4 dihedrals. The line that best seems to match S. Kimball's guidebook description of gritty flakes seems to start just to the left of the left-most dihedral (perhaps S. Kimball can clarify?). Step up, find pro in a horizontal to the left, move up into the dihedral with face holds on the right. Gain the top of a flake. Here you step right with a bit of an airy feeling aiming for a prominent jug/bucket to the right. Find a small cam placement before you reach the bucket. Note, the bucket does not feel solid (hence, the taste for a TR); however, you can face climb on smaller features & avoid this bucket. Fire to the top. 60 feet.
You can walkoff down the South face and exit East.
Mostly cams, slings, a bit of trust. The TR anchors are #0.75 to #1 Camalot size.
