Big Jacks Creek Wilderness

The Big Jacks Creek Wilderness, in the Big Jacks Creek Basin, consists of rugged canyons, streams and plateaus that provide habitat for redband trout, mountain quail and bighorn sheep, as well as two sensitive plant species. The basin ranges in elevation from 2,808 to 5,872 feet and drains a sagebrush-covered plateau dissected by rugged, sheer-walled canyons that are as much as 650 feet deep. Big Jacks Creek flows north into the Bruneau River, a tributary of the Snake River. The basin is covered by big sagebrush, low sagebrush, salt desert shrub, and riparian vegetation communities.

Precipitation totals about 7 inches a year. The station sits about 2,500 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.
