Red Pillar is part of the Arrow Wall. I think it's one of the nicest 5.5 in the Gunks. Pitch One has two pitons (?) but run out between them. It's a little bit stiff on 5.5, but hey, that's Gunks climbing.
Pitch 1: Climb the broken corner to the top of the pillar. Go up the clean part of the face to GTL. A bit run out between the pitons, a few small cams should make it feel better. (5.5, 100'
Pitch 2: O, what a nice climb :). First, move right about ten feet, climb slab to a small ledge, then climb the obvious right facing corner to a roof. Exit the corner left (crux 1), then up the face to an obvious V-notch. Go over the V-notch (crux 2) and to the top. (5.5, 120'
* I didn't do the original line, which goes up left, so I won't plagiarize guidebook. I did the variation which is what I described above.
To Rappel, walk right fifty feet, use the bolt anchors on Arrow. Two sixty meter ropes should get you to the ground. Be ware, Arrow wall is very popular, so make sure you paid attention on climbers.
Base. Climb the broken corner.
Pitch 1: Up the clean face to GTLedge.
Pitch 2. Sorry for the trees, I'll try to take a better picture.
