I basically headed up the west side of Mount Patterson and encountered quite a bit of deadfall. I was able to traverse over to the north shoulder via a use trail that reaches the saddle between Patterson and Pt 11008. Nisa was a straightforward hike down the ridge from Patterson. I descended via game trails from the saddle between Nisa and Patterson.
Hiked all three peaks from the Green Mountain Trailhead. The water level of Tonahutu Creek was high, so crossing it to begin the climb up Nisa Mountain's northwest ridge was exciting. Big Meadows was swarming with mosquitos, but the views from the top of Mount Patterson were worth it.
