Devil's Thumb Trail

Description:

The Devils Thumb trail begins on the east at an elevation of 9,030 feet and travels north and west to intersect the Corona trail at 11,920 feet. The trail can be accessed from the Devils Thumb Park trailhead on the west and the Hessie trailhead on the east. From Hessie travel west for about .8 miles to where this trail intersects the Devils Thumb Bypass trail. The bypass trail travels up the east side of the valley through a series of open meadows and rejoins the Devils Thumb Trail about .1 miles above the Woodland Lake trail. It is about .1 miles shorter. The Devils Thumb Trail crosses the south fork of Middle Boulder Creek and travels along the south side of the creek for about .4 miles before crossing it again and heading north. There is a beautiful waterfall just a few hundred yards from the first crossing. You’ll pass the Lost Lake trail heading south to Lost Lake. After crossing the creek the second time the King Lake trail splits off to the west toward King Lake and Corona Pass. The Devils Thumb Trail continues north for about .9 miles before intersecting with the Woodland Lake Trail. Most of this portion of the trail travels through open meadow. It shortly rejoins the Devils Thumb Bypass Trail beyond the Woodland Lake Trail.
From the intersection, the trail begins its climb toward Jasper Lake at the upper end of the valley. It follows an old road bed off and on up the east side of the valley. Some patches of wild huckleberries can be found along the way. As you climb the east slope you are afforded many beautiful views of the peaks to the west. The Diamond Lake Trail is intersected about 1.6 miles from the intersection. This trail heads sharply away from the Devils Thumb trail in the opposite direction as it climbs the ridge and drops down to Diamond Lake. The trail levels off some a short distance from the Diamond Lake Trail. It then travels through some wet meadows to Jasper Lake in about .5 miles. There are several false trails leading off the main trail. Stick to the old road bed when in doubt. The trail passes below Jasper Lake. A trail splits off to the right to the lake and then rejoins the main trail farther west. Jasper Lake sits in a bowl surrounded on the north by rock faces. Storm Lake is located on a bench above and the the northwest of Jasper Lake. It looks like a fairly strenuous climb up to Storm Lake. Camping is permitted in designated sites only around Jasper Lake. Jasper Lake contains brook and cutthroat trout.
The trail makes a gradual climb through some wet meadows and spruce forest for another 1.1 miles to Devils Thumb Lake. It gets steeper just before you reach the lake. It follows the south shore of the lake before beginning the steep climb to Devils Thumb Pass. The trail here is narrow and very steep. At the top it breaks out onto the alpine tundra. It then descends to intersect the Corona Trail.
