West Face/Northwest Ridge, Class 2
From Mill Creek Summit, bushwhack east straight uphill through a pine forest with copious amounts of downed trees to navigate. High up, scramble up a talus slope to reach a rocky point (at about 9,440 feet) on the northwest ridge. From this rocky outcrop, follow the ill-defined ridge southeast then south to the rocky outcrop that is the summit of Peak 9561. Skirt the right/south side of a forested ridge hump on the way. The northwest ridge is forested and has lots of blowdown to weave around with a gravel/sand base and ground boulders. The ridge has two minor ups and downs before reaching the summit. There is a modest cairn on the rocky summit.
