Washakie Wilderness

Chief Washakie was a historical figure and leader of the Shoshone tribe of Wyoming. In 1972, the Stratified Primitive Area was joined with South Absaroka Wilderness to form the Wilderness area (Wyoming's largest) that now bears his name. Yellowstone National Park borders to the northwest, Teton Wilderness to the west, and the Wind River Indian Reservation to the southeast–a combination of lands that stretches across a tremendous part of western Wyoming and is one of the greatest wild regions of America. In the southern Absarokas, you'll find broad, flat-topped mountains and plateaus separating narrow valleys that have been deeply incised with exposed volcanic strata.

The line is the average temperature and the bars are average precipitation at Cody 21 SW, 22 miles from the center point at 5,840 feet, station USC00481855 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 12 inches a year. The dotted line is average snowfall, about 45 inches a year on the same inches scale. The station sits about 5,600 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
