Miriam Peak is located in one of the most remote areas of the contiguous United States, in the northern Wind River Range in Wyoming. It is accessible via one of several trailheads.

Access from the East
Trailhead: Cold Springs
Trail: Ink Wells
Distance: 11 miles
Indian reservation - permit required

Follow the Ink Wells Trail west until it intersects with the Glacier Trail at the south end of Big Meadows. Follow the Glacier Trail south until you reach Dinwoody Glacier. Cross the glacier and ascend Bonney Pass, the obvious saddle between Dinwoody and Miriam Peaks.

Access from the South
Trailhead: Elkhart Park
Trail: Pole Creek Trail to Titcomb Basin Trail
Distance: 19 miles

Follow the Pole Creek Trail NW to the trail split at Eklund Lake. Turn north onto the Titcomb Basin Trail and follow it all the way past the Titcomb Lakes. Continue north to Bonney Pass via a low use trail. The trail disappears in some places, but the open country is easy to navigate.

Access from the North
Trailhead: Trail Lake Ranch
Trail: Glacier Trail
Distance: 25 miles

Follow Glacier Trail south all the way past Floyd Wilson Meadows to the Dinwoody Glacier. Cross the glacier and ascend Bonney Pass, the obvious saddle between Dinwoody and Miriam Peaks.

Route Description

The ascent begins from Bonney Pass. The route from the Pass to a false summit just short of the true summit is an easy class 2 scramble through mixed snow and rock. However, the final ascent requires crossing a 10ft narrow and very exposed jagged ridge with a 15 drop down to a notch and then a 25 ft Class 4 ascent to reach the summit. This entire last section is very exposed. A fall would be fatal. There are 2 lesser peaklets on the eastern ridge to the summit. It takes less than an hour to reach the false summit from the Pass.

Essential Gear

Ice axe and crampons may be required to climb Bonney Pass depending on the weather. If crossing Dinwoody Glacier from the north, rope is highly recommended. Snowshoes are required in winter and after heavy snowfall. Rope and protection is recommended for the final section.
