The United States Congress designated the Big Jacks Creek Wilderness in 2009 and it now has a total of 52,684 acres. All of this... more » wilderness is located in Idaho and is managed by the Bureau of Land Management. The Big Jacks Creek Wilderness is bordered by the Little Jacks Creek Wilderness to the northwest. They are separated by a natural gas pipe line and dirt road.
The wilderness, in the Big Jacks Creek Basin, consists of rugged canyons, streams and plateaus that provide habitat for redband trout, mountain quail, sage hens, mountain lions, mule deer, antelope, bobcats, coyotes, and bighorn sheep, as well as two sensitive plant species. The basin ranges in elevation from 2808 to 5872 feet and drains a sagebrush-covered plateau dissected by rugged, sheer-walled canyons that are as much as 655 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. The sagebrush communities are most common; low sagebrush types are found primarily on shallow, poorly drained soil, and big sagebrush types are associated with deep, well-drained soils.
Lush riparian vegetation grows along perennial reaches of the creek and generally includes shrubs of willow, rose, and currant as well as sedge and bluegrass in meadow areas. Poison Ivy is abundant in the riparian areas. Beaver colonies are also found along the waterways.
Access to the basin is by way of a network of dirt roads in the southern part of the basin and hiking trails in the wilderness. The Parker Trail is the only mapped hiking trail into the wilderness. Other trails fall into the game/stock trail category. less «
