Big Jacks Creek Wilderness

Big Jacks Creek Wilderness is composed of about 52,826 acres in the Big Jacks Creek drainage. About 35 miles of Big Jacks Creek is designated as "wild and scenic river." Big Jacks Creek Wilderness is separated from Little Jacks Creek Wilderness by a pipeline and the maintenance road that runs along it.

The landscape is a mix of streams, rugged canyons and plateaus where the elevations vary from about 2,800' to about 5,900'. Some of the canyons sport walls almost 700' high.

The streams support populations of redband trout while the majority of sagebrush-covered land hides small herds of bighorn sheep and pronghorn antelope. The perennial streambeds tend to be riparian zones with willows, wild roses and currant bushes.

There are some small meadow areas that grow a nice carpet of sedges and bluegrass. The better the drainage properties of the soil, the taller and thicker the vegetation that grows on it. You'll find plants like Idaho fescue, Thurber needlegrass, black sagebrush, low sagebrush, bud sagebrush, bluebunch wheatgrass, Indian ricegrass, wild rose, currant, sedge and willow on different parts of the property.

The easiest way to get into the property is via a series of dirt roads that wind around the southern part of the wilderness. Most of the hiking trails wander up and down the canyons because the volcanic countryside is so broken and cut so deeply by erosive forces.

There are two primary hiking/horseback riding trails in the wilderness. Both trails are an excellent introduction to what it's like to go hiking in the Owyhee Canyonlands, ie: you need good map and route-finding skills and you must be able to carry all the gear you need across steep and rocky terrain.

The Duncan Creek/Zeno Canyon Trail is an 8-mile round trip along Duncan Creek and is rated as "challenging." After disembarking at the trailhead, head southeast across three wet, spring-fed meadows to the gully that drops into Zeno Canyon. Where the two creeks come together, contour along the wall of the gully staying about one hundred feet from the bottom of the gully. When you come to the talus, there is a steep descent down a chute of steep, loose scree to the floor of Zeno Canyon. At that point you'll be about 1/2 mile from the trailhead and 460' down the hill. Down that canyon you'll come to a spectacular, 60' waterfall that drops over the rim of the canyon. Most folks follow the streambed about 4 miles up from the trailhead, to the Buncel Place, then they turn around and return.

The other trail (Big Jacks Creek Canyon/Parker Trail) is about 1.2 miles long (with a drop close to 560') and similarly challenging. It descends to the creek level and has you following intermittent trails until you can see the canyon bottom. At that point the instructions read "if you can find it," referring to a trail that actually descends to the canyon floor. Once there, there are trails running in all directions but all trails have frequent stream crossings.

Big Jacks Creek Wilderness is in the Owyhee Desert, part of the Basin and Range physiographic region. The streams in this area drain to the Bruneau River, which then empties into the Snake. When the Big Jacks Wilderness was formally designated in 2009, the Duncan Creek Wilderness Study Area was included in it.
