Elevation: 11,039 ft
Climbing and access information for this peak is on Page 257 of the book.
Atlas Peak, the 119th-tallest peak in Idaho, is rarely climbed but is well worth the effort. The peak is becoming more popular, with ascents from both its west and east sides to reach the peak’s North Ridge. You can also access the peak by traversing the ridge from the summit of Peak 10536, approximately a mile to the north.
Atlas Peak is documented with two elevations. The 15-minute Muldoon Canyon quadrangle puts the elevation at 11,039 feet. However, the [newer] 7.5-minute Smiley Mountain quadrangle assigns an elevation of 11,020 feet. Steve Mandella and team’s recent ascent (2017) measured the summit elevation at 11,031 feet. For now, I will stick with the original figure (11,039 feet). USGS Smiley Mountain
This peak is accessed from Muldoon Canyon, located west of Star Hope Campground in Copper Basin. The Copper Basin Loop Road takes you to FS-510 at the loop’s south end. The peak can also be accessed from the east from the Lake Creek Recreation site, just off the Copper Basin Loop Road.
Routes, Class 3
The peak can be reached from the east by climbing up the Lake Creek drainage and using the trail to Golden Lake. From here, climb west to reach the North Ridge of Atlas Peak as shown on George Reinier’s route shown below.
Steve Mandella, Margo Mandella and Bruce Dunham climbed Peak 10536 and Atlas Peak together as a loop route from the west. Read about their route using this link. From either direction, the North Ridge to the summit is of Class 3 difficulty.
