Route we took up the ramp illustrated (yellow dots show areas hidden in photo). The lower yellow-dotted part was up through a rok chimney and then near-vertical snow for a bit. After that pretty straight forward but crappy conditions this day. The upper brown part on the ramp was a rock field with a few inches of ice/snow above the rock so that I had to chop through it or step on it and fall a foot or two into it. Made for very slow going.
