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. 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, mostly ATVers, as a worn trail leads to the summit from nearby UM Pass. 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 (UNDER CONSTRUCTION)Note: 4WD is no longer necessary in the summer. The road up Seven Mile Valley is well graded. Cars should have no trouble making it to the jeep trail turnoff. Once on the jeep trail, moderate clearance is required.
