Mount Marvine, also known as Sawtooth Peak, or the Blade, is the enduring remnant of a high volcanic plateau. Landslides, wind and water erosion gradually stripped away hardened ash and lava deposits, leaving only a narrow, jagged profile of rock. As a testament to this erosion, the mountain is surrounded by 54 square miles of landslide debris.

Some have compared Mount Marvine's profile -when viewed from the north- to the much grander Matterhorn. Without a doubt, the same forces of nature that carved the Blade also helped craft Monte Cervino and its neighbors.

Part of the massive Marysvale Volcanic Field, the peak's flanks are covered in over 300 meters 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.

Seven Mile Valley passes along the southern edge of the mountain, winding its way through several large glacial moraines. These moraines are the
largest in the area, deposited by several 2 to 4 mile long glaciers. At several points, you can look up the canyons surrounding Seven Mile Valley and see the high cliffs from which the glaciers descended.

Mount Marvine's slopes were battered and scorched by a wildfire in 2002; however the vegetation is making a steady recovery.

The peak is located in Utah's Fishlake Wilderness, less than 2 miles from the area's namesake. On a clear day, the summit offers some of the best views in south-central Utah. Points often visible include Fishlake Hightop, the Mytoge Mountains, Mount Terrill, Windstorm Peak, Thousand Lakes Peak, Steves Peak, Mount Nebo and Capitol Reef National Park.

Mount Marvine is ranked #94 in Utah by prominence.

Getting There

4x4 vehicle with 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 1 mile. Mount Marvine will be visible on your right. While passing near the northwest side of the peak you will reach a jeep trail leading northeast toward the summit ridge. Follow this trail until it reaches the high ridgeline at an elevation of about 10,400'. Park here or slightly farther down the trail near Lost Fork Creek. There are no marked trails here. In order to reach the summit, one must scramble up the NW slope. The easiest route, "Martin's Ladder", follows the ridge as it curves SE. Expect a minimum of Class III exposure in some spots.
