The trail into Fisher Basin is steep and scenic. Massive Mt. Logan looms ahead. Lush meadows bloom in pinks, reds, purples, whites, and yellows. Deer and smaller mammals abound. Black bear are often seen grazing in the meadows, eating huckleberries. Just prior to protection under the National Park Act in 1968, one of the last grizzly bears in the North Cascades was shot here. The Fisher name comes from the Fisher brothers who ran a trap line here in the early 1900s.
Fisher Camp is at the edge of the meadows, two miles (3 km) beyond the pass. Leaving the meadows, the trail descends gently, entering the mature silver fir forest of the Fisher Creek Valley. Creekside Cosho Camp is in the deep forest, 6 miles (9.6 km) beyond the pass. This is an entirely different life zone, home to martin, owls and their prey, including flying squirrels, voles, and deer mice. Continuing down valley, the forest gradually changes to mid-elevation species of western redcedar, western hemlock and cottonwood in stream flats. A mile from Junction Camp, an old trapper's cabin is semi-hidden just off the trail. Rock Cabin was built against a great rock, using the rock as one wall. This unique cabin has been stabilized by the National Park Service, and today serves as a reminder of the human history in this remote valley.
Junction Camp is situated near Fisher Creek on the ridge overlooking Thunder Creek Valley. Views are good from this area, including a glimpse of Boston Glacier in the distance. From Junction, you have several options: retrace your steps to the Easy Pass trailhead; hike down the Thunder Creek Trail 10 miles (16 km) to Colonial Creek and State Route 20; or head 17 miles (27 km) up and over Park Creek Pass and into the Stehekin Valley.
