This trip was totally set up by Irina and she invited me along as thanks for the help I had given her during her stay in Ecuador. I didn't have to plan a thing! What a treat. As a bonus she takes good photos. You'll see some of hers below. Anything with an "i" before the number is her work.
Unfortunately we had to stop just under the summit (30 meters maybe). Edgar discovered an uncrossable crevasse just beyond the wall. Still it was an excellent and very interesting climb through a maze of crevasses on a mountain few people attempt.
