There are several ways to approach this broad-sided, 9,652-foot peak just west of Mammoth Hot Springs, but the top route begins on the Sepulcher Mountain Trail at Mammoth, ascends the summit, loops back on the Glen Creek Trail, and crosses Snow Pass to return to the trailhead. Hike west across an old burn area now strewn with wildflowers in summer, then begin gaining for a total of 3,400 feet. You’ll get views across the Absaroka-Beartooth Wilderness and Gallatin National Forest, and down into Mammoth and Gardiner. A 360-degree panorama opens at the summit. Switchback your way down the peak’s southeast ridge and swing east to approach Snow Pass and your route back to the trailhead. Be on the lookout for moose, bighorn sheep, mountain goats—and grizzlies. This is a favorite habitat for bears, so be loud and hike in a group.
