? (WINTER) HOLD ON! If you don't have much high-elevation, winter climbing experience, be careful in your planning and take a partner. All 14er routes are more difficult and more dangerous in winter.


This trailhead is used to access both Argentine Pass and Horseshoe Basin. Take U.S. 6 to the west end of Keystone. If you are driving east on U.S. 6, take the exit for Montezuma Road before U.S. 6 begins its climb to Loveland Pass. If you are driving west (from Loveland Pass), turn left into the River Run area of the Keystone Ski Resort. Take another quick left and drive a bit to get to the Montezuma Road.

Drive ~4.3 miles on the Montezuma road and turn left on the 260 (dirt) road. There is a large parking area at the start of this road. From the parking area, drive 4.5 miles along Peru Creek to the Argentine Pass trailhead at 11,050', just below the Shoe Basin Mine. The road is gated beyond the trailhead.


From the parking area, walk northeast a short distance up the road and pass the gate, near the Shoe Basin mine - 1. Continue less than 0.5 mile and turn right onto the marked Argentine Pass trail - 2. Cross Peru Creek ( 3 but now there's a bridge, I think) and continue southeast on the great trail. After weaving through willows, traverse a slope ( 4) and exit the trees, near 11,600' - 5. Above 11,800', turn sharply left and continue north along Argentine Peak's west slopes - 6. Cross a large gully ( 7) and another, more-rugged one, near 12,800' - 8. Ascend a long stretch ( 9) to reach Argentine Pass at 13,200' - 10.

Argentine Pass is near the center of the long ridge between 14ers Mt. Edwards (north) and Argentine Peak (south). If you'd like to add Argentine Peak to your route, it's approx. 2 miles round-trip to summit Argentine Peak from the pass (refer to the Argentine Peak: Northwest Ridge route). For Mt. Edwards, turn left from the pass and continue north along the Continental Divide - 11. After a short distance, Edwards pops back into view as you hike towards unnamed point 13,484' - 12. Continue over Point 13,484' ( 13) to reach another bump on the ridge - 14. Reach the final pitch ( 15 and 16) and ascend 350' ( 17) to reach the summit - 18 and 19.


This route uses a western approach, from Peru Creek. The southwest ridge can also be climbed using an eastern approach from Georgetown and the Waldorf Mine, 4WD road.
