oldgoat, I think I've skied the area you mentioned. From top of Emigrant you go backside and climb up just a bit to right. In this picture it's right of the right red line where the large rock sticks up.
A guide with the last Epic Gathering took several of us, myself & I think Near Nyquist & alexzn to what he called the attic?
Yes, I took you there the last time the Epic crew was at Squaw:-) But that was not the terrain JayT sketched. This is the view from that part of the attic from today.
