Whiskey Mountain, Mountain summit in Wind River Range, Wyoming, US

Whiskey Mountain is a 3,401-metre summit at the northeastern edge of the Wind River Range in Fremont County, Wyoming, about 12 km south of Dubois. Its ridge rises between the Jackeys Fork valley to the north and the West Torrey Creek valley to the south. Conifers grow on the north and east slopes, while sagebrush and bunch grasses cover the drier exposures.

Early trappers and explorers during the fur trade era found a cache of whiskey on the mountain slopes, which gave the peak its enduring name. This discovery became part of the region's frontier history.

The mountain's name comes from a hidden camp of trappers and fur traders during the rendezvous era. Since the mid-20th century, a bighorn sheep herd has wintered on the north slopes, where a 1931 fire left limber pines and Douglas firs among charred stumps.

The usual start is Trail Lake Ranch at the end of Trail Lake Road above Trail Lake. From there the Whiskey Mountain Trail heads west into the south flank; above treeline you can leave the trail and climb off-trail to the summit, gaining 1,100 metres in about three hours (Yosemite Class 1). The Whiskey Creek Trail runs from Whiskey Basin southwest to join it about 2 km northwest of the mountain.

The slopes here support the largest winter population of Rocky Mountain bighorn sheep in North America, making it a critical refuge during harsh months. Visitors hiking in winter may spot these animals grazing on wind-cleared grass that remains exposed on the ridges.
