Wilderness Profile


Just three miles off of Interstate 80, Castle Peak Potential Wilderness is among the most scenic areas in the Tahoe National Forest. Home to extraordinary old-growth red fir forests and the little Truckee River, Castle Peak provides clean drinking water to residents of Nevada County.

Underwood Potential Wilderness

Managing agencies: Six Rivers and Shasta-Trinity National Forests.

Size: Approximately 21,623 acres.

Location: Trinity and Humboldt counties between the towns of Hyampom and Salyer.

Description:

  • Bisected by the Wild and Scenic South Fork Trinity River.
  • Noted for its outstanding spring wildflower displays.

The Underwood proposed wilderness is located along the Wild and Scenic South Fork of the Trinity River. The river has created a steep canyon, which occupies much of the area. Recreational opportunities are plentiful: rafting and boating in the spring, followed by swimming in the many pools during the summer.

Visitors can often see salmon and steelhead holding in these same pools in the summer and spawning in the fall. The Underwood proposed wilderness hosts a fall run of chinook salmon as well as a lesser run of coho salmon. Fishing is allowed in this section of the river and attracts many anglers.

For some 5 miles, the South Fork Trail winds through the steep and rugged terrain above the river. This trail is popular with hunters and hikers, and is used for river access by fishermen.

South Fork Mountain, which forms the approximate western boundary to the unit, is notable for being the longest ridge found in the western hemisphere. It provides important habitat for mountain lion and bear, as well as raptors such as eagle and osprey. Along the river, both otter and mink are found. Native Americans lived along the river and enjoyed the once abundant steelhead and salmon runs.
