Backpacked in from the Iron Gate trailhead. Road in very rough condition - high clearance required. Hiked up to Armstrong, then Arnold the following day. Spectacular views of distant peaks and the beautiful Horseshoe Basin!!
Came in via Windy Peak (also climbed) and made camp near Horseshoe pass. Strolled up Armstrong in the evening and got a few pics by the monument. Snow free, no routes, but easy to find your way up. Very cool summit area, just immense, and great views of the basin.
