Sacajawea Peak

Sacajawea Peak is the highest summit in the Wallowa Mountains and one of Oregon's most prominent peaks. Rising to about 9,843 feet from the granite and marble core of the range, it stands in remote northeastern Oregon, well outside the more heavily traveled corridors of the Cascades. Its nearest higher terrain lies roughly 126 miles away near Pinyon Peak in Idaho, giving the mountain notable topographic isolation.

The surrounding Wallowa-Whitman National Forest and Eagle Cap Wilderness protect a vast alpine landscape of glacial valleys, high ridges, meadows, lakes, and rugged limestone and shale terrain. Sacajawea's geology is especially distinctive for Oregon: the east face is formed by pale Martin Bridge Formation marble, while darker Hurwal shale appears along the southern ridge. From eastern and southern aspects, the mountain appears as a broad red-scree summit; from the north and west, gray limestone cliffs dominate the view. Mountain goats and golden-mantled ground squirrels are often seen in the upper basin and summit area. The peak's official name uses the spelling "Sacajawea," though the Shoshone woman associated with the Lewis and Clark Expedition is more commonly rendered "Sacagawea." A 1999 proposal to standardize the peak's name as "Sacagawea Peak" was rejected by the U.S. Board on Geographic Names.

Hurricane Creek Trail / Thorp Creek East Ridge

The standard route begins at Hurricane Creek Trailhead (approximately 5,900 ft), following the Hurricane Creek Trail south through forested valley terrain before turning onto the Thorp Creek Trail. The trail continues through alpine meadow to Thorp Creek Meadows at roughly 7,600 to 8,000 feet, the standard overnight camp and the last reliable water before the upper mountain. Above the meadows, climbers leave the maintained trail, cross Thorp Creek, and ascend open terrain to the base of the east ridge at around 8,200 feet. The ridge involves Class 2 to low Class 3 scrambling on marble, limestone, and loose Hurwal shale, with gravel-covered slabs and unstable scree creating sustained poor footing. No established trail exists above treeline. The ridge leads northwest to the summit, where a cairn marks the high point. Round trip is approximately 15 miles with around 4,900 feet of elevation gain.

Alternative routes include an approach from Ice Lake via the Hurwal Divide saddle on the southeast, and a ridge traverse from Matterhorn to the south, which involves Class 3 sections around several gendarmes and is longer and more complex than the east ridge standard.

Key Landmarks

• Hurricane Creek Trailhead (~5,900 ft)
• Thorp Creek Meadows (~7,600–8,000 ft)
• East ridge base (~8,200 ft)

Mid-July through mid-September is the standard climbing window. Early-season snow may block the Thorp Creek approach through late June or early July, and high water may require wading at creek crossings. Mountain goats are often seen in the upper basin and summit area. Afternoon thunderstorms are common in summer; plan to clear exposed ridge sections above 8,000 feet by midday.
