To reach the Ruth Lake Trailhead, drive Highway 150 35 miles north, and east of Kamas or 43 miles south of Evanston. There is a sign that marks the trailhead (west side of the Highway).
The well-used Ruth Lake Trail heads west from the trailhead (10,120 feet) for one mile to Ruth Lake (10,350 feet). The trail is an easy hike and there are only a few short uphill sections. The entire trail is very beautiful and there are views of spectacular and rugged Hayden Peak to the east. Ruth Lake itself is on a very scenic setting. From Ruth Lake, follow the hiker-made trails west to Hayden Lake. From Hayden Lake, head north and then west along the base of the mountain from Hayden Lake. From Cutthroat Lake (10,400 feet), "Cutthroat Pass" to the south is visible. This is your objective. Scramble up to the pass (10,700 feet). There is some boulder-hopping and this is the toughest part of the climb, but it still isn't bad by Uintas standards. There are good views from here of Cutthroat Lake located below and north of the pass. There are also good views of the High Uintas Wilderness to the northeast. From the pass, head up the very steep slope to the west. There is some scrambling and boulder-hopping required before reaching the summit. Near the summit is often a snowfield that blocks the route. This route is easy, and an ice axe can be of some use well into July, though most could do without. Round trip distance is about 5.6 miles.
A good pair of boots is needed.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
