This was a interesting trip, we ended up doing a little more than what was needed. But the scenery was decent.
Two of our group of 5 turned back on the summit of Moose Peak when they saw the remaining distance. Robbin, Josh Lewis and I continued on to the summit circling around the more direct east side. We returned via the low trail through Grand Valley.
I started the day at Dose meadows, hiked up to Lost and then Cameron pass. From Cameron I traversed the ridge to the saddle between McCartney and the adjacent unnamed peak of nearly identical height. My choice at that point was simple: press on toward Obstruction Point (my objective) or summit McCartney and then press on. Tired and weary I pressed on, descending the Lillian glacier and then clawing my way back up to Low pass. I now realize my mistake and will return one day (if I can ever get back to the Olympic Range) to climb McCartney.
