Mount Terrill - also known as White Knob - is a small, rounded peak north of Seven Mile Valley high on the Fishlake Plateau. Although not much of a technical challenge, this peak is remote and offers incredible views of south-central Utah's Wasatch Range. On a clear day, points visible from Mount Terrill include Fishlake Hightop, Mytoge, Mount Marvine, Windstorm Peak, Monument Peak, Thousand Lakes Peak, Mount Nebo and Capitol Reef National Park.

The mountain sees few visitors, except perhaps the occassional Boy Scout Troop or National Forest surveyor. Heavy snowfall accumulates late October through March. In warmer weather, herds of Elk frequent the mountain slopes, grazing on the short grasses that grow there. Numerous springs feed nearby Lost Creek and Harves River reservoir.

Part of the massive Marysvale Volcanic Field, the peak is covered in 250 to 400 feet of densely welded, vesicle-poor pyroclastic flow deposits overlying Paleocene Flagstaff Limestone. These volcanic deposits were left from an ancient eruption of nearby Monroe Peak Caldera.

Getting There

4x4 with good clearance highly recommended.

From Richfield, Utah
From I-70 take exit 119 in Richfield. Follow 119 east through the town of Glenwood and up to the junction with Highway 24. Take 24 south past Koosharem Reservoir until it climbes to meet Highway 25 (toward Fish Lake).

Follow Highway 25 northeast past Fish Lake and Johnson Valley Reservoir. At the northwest corner of Johnson Valley Reservoir is a dirt turn off. A sign proclaims this to be Seven-Mile Valley. Follow this dirt road (NF-319) for about 5 miles. You will pass Mount Marvine on your right. Eventually, you will reach a jeep trail and a sign directing you to Mount Terrill. The jeep trail (NF-42) skirts the south side of the mountain. Follow the trail until it reaches the high ridgeline at an elevation of about 10,250'. Here you will find a trail that heads due north toward the summit. Although the trail is not well maintained, it should be clear where the trail leads and where the summit lies. GPS may be necessary, especially in winter, as snowdrifts cover the trail.
