Peak 8664 is located in the northwest corner of Copper Basin. There are four ranked summits that surround Fox Creek: Peak 8664, Peak 9533, Peak 8763, and Peak 8146. They make for a fine, one-day outing that is entirely off-trail and covers 10.2 miles with 4,350 feet of elevation gain round trip. Peak 8664 is first up and is close to the mouth of the Fox Creek drainage. It is due west of the end of Fox Creek Road. I saw more big game on this four-peak day than any other hiking day during 2020 and brought home a nice shed elk antler. USGS Big Black Dome

East Ridge, Class 2
The Climb
From the end of Fox Creek Road, scramble west up a steep sagebrush slope and skirt the left/south side of a rocky buttress (Point 8346). Descend 115 vertical feet to a saddle that sits at the base of the east ridge of Peak 8664. Scramble west up the thinner scrub on the east ridge to reach the summit of Peak 8664. The summit has a small cairn on the summit ridge crest area.
Southwest Ridge, Class 2
The Descent
From the summit, descend southwest on easy scrub and make a final jog right/west to reach the saddle at the base of the southwest ridge of Peak 8664. This is the connecting saddle between Peak 8664 and Peak 9533. This concludes the first leg of today’s four-peak odyssey. Peak 9533 is up next.
