We did this as a backpack with at that time 78-yr-old Bob Martin, who was working on Utah county and state high points. Bob had sustained injuries earlier that year, so was thrilled to find out he could still do a backpack. After a pleasant pack in from Henry's Fork TH, the 4 of us camped at Dollar Lake. Didn't stay long on the peak due to threatening clouds gathering.
I was joined by my friend Duane and my father, who was then almost 80 years old. He had no illusions of going to the summit, but was anxious to enjoy a vigorous hike in the high wilderness. He turned around at about the 11 mile point for a 22-mile round trip. Duane and I approached via Gunsight Pass, taking the cross-country shortcut to Anderson Pass, then south up the summit ridge of Kings Peak. We completed the 28.8 mile round-trip hike after 1 AM the next morning. It was the longest day hike I have ever experienced, and a very enjoyable one at that.
