General Conditions

Last Updated July 23, 2014

Summer has arrived in the North Cascades. The days are long and the past week was very hot and has turned to milder temps with lots of rain fall. The remaining high country snow is melting quickly and lots of rain is resulting in rivers and streams running swift and high. Backcountry travelers should be prepared for a variety of weather conditions and smoke drifting in from fires on the east side of the park.

Many higher elevation trails are transitioning from solid snow cover to patchy snow, but some mountain passes are still completely snow covered. Expect significant snow coverage beginning around 6,000' depending on slope and aspect. A variety of wild flowers are blooming along the trails and in the meadows. Trail crews are busy clearing brush and making repairs along the snow-free trails. Streams can quickly rise higher due to both rains and rapid snow-melt. Always check a current weather forecast and local conditions before heading out. Backcountry travelers should be well prepared for a variety of conditions, and leave an itinerary with someone at home.

Summer Conditions Note: Because of rapidly changing conditions, actual ground conditions may be different than reported in the list below. Some trails or portions of trails have yet to be surveyed at higher elevations due to snow conditions. Conditions change constantly with weather events such as wind storms, rain, heavy snow melt on sunny days, and fresh snow. The report below lists last known conditions or projected conditions based on this time of season in past years and/or based on known conditions on similar trails elsewhere in the park. Please plan accordingly!

Whenever and wherever you travel in the wilderness, please be safe and touch the wilderness gently. Know and practice Leave No Trace camping and hiking. Please email us if you have trail conditions to report.


Closures and Notices

Hard-sided food canisters are required at select backcountry camps and cross-country areas. In order to protect visitors and wildlife and to maintain the wilderness character of North Cascades National Park Complex, hard-sided food canisters are required from June 1 to November 15 for camping at ten backcountry camps and all or parts of five cross-country zones. More information on food storage requirements, including maps of cross-country zones where canisters are required can be found here. Full statement on policy change.

Boulder Creek Trail CLOSED due to the Lone Mountain Fire. The lightning-caused Lone Mountain Fire ignited on July 15 and is burning in steep terrain. The fire has burned across the trail and the trail is closed until further notice.

Planned closure of Cascade River Road beginning September 8, 2014. Cascade River Road will be closed to all methods of traffic, including foot and bicycle traffic, at the Eldorado Creek parking area from September 8, 2014, until late October. The road will be closed for significant road repairs at Boston Creek (1.2 miles from Cascade Pass Trailhead). Once the road closes, and until work is completed, there will be no visitor access in either direction through the closure area. Trails affected include all Cascade Pass area trails. Affected climbing area access includes all routes in Boston Basin. See Road Conditions for full details.

Trail and road CLOSURES in adjacent National Forest lands due to proximity of the Lone Mountain Fire and the Carlton Complex Fire. Except for the Lakeshore Trail (Tr. #1247), all trails in the Lake Chelan-Sawtooth Wilderness are closed. This closure includes the following U.S. National Forest trails that provide access to North Cascades National Park and Lake Chelan National Recreation Area: Twisp Pass Trail (Tr. #432); Copper Pass Trail (Tr. #426); South Creek Trail (Tr. #401); Reynolds Creek Trail (Tr. #402); War Creek Trail (Tr. #408); Chelan Summit Trail (Tr. #1259). The Twisp River Road is closed at Eagle Creek. All trailheads west of Eagle Creek are inaccessible.

East end of Diablo Lake Trail CLOSED at the suspension bridge. A massive rockslide that came down in early 2010 still blocks any hiker passage from the Diablo Lake Trail to the haul road, ferry boat, or Ross Lake from this trail. Work on the slide will be ongoing in 2011 and may include blasting. The remainder of the trail is unaffected. See map of closure area.

Hiker, stock

Snow-free and clear of down trees.

Since recent fires have reduced vegetation, soils are subject to erosion and water runs off the landscape rapidly--hikers should be cautious at stream crossings during rain events as waters may rise rapidly. Down trees can also be common.

Ross Lake 1600', Stillwell ~ 2500', Whatcom Pass 5200'

Hiker only from Little Beaver to Stillwell.

Cleared of down trees to junction with Big Beaver Trail. Perry Creek and Redoubt Creek are both quite braided and require wet fords. Route across Perry Creek delta is flagged.

Pacific Crest Trail North (Bridge Creek Trail)

Bridge Creek Trailhead: 4640'

Hiker, stock

Snow-free. Several small trees down west of Hideaway Camp, all easily passable. Recently brushed between Hideaway and South Fork. Several wet stream crossings.

Rainbow Loop (Stehekin)

Elevation 1200' to 2200'

Hiker, stock

Snow-free and clear of down trees. Hikers use caution as blow downs are common due to 2010 wild fire.

Hard-sided food canister required at Sourdough and Pierce Mountain Camps June 1 - Nov. 15. Pets and hunting are not allowed past the National Park boundary (about 2 miles from trailhead).


Stetattle Creek

Trailhead at 900'

Trail clear of snow with a few down trees to about 3000'. Patchy snow to the ridgeline at 5,000'. Thornton Lake camp sites and composting toilet are melted out. Lake is 75% frozen. Scramble route to Trappers Peak has patchy snow.

Getting to the campsites from the ridge; the trail to lake is steeper than most trails and can be very slippery when wet or icy. Just before reaching the lake outlet (to reach Thornton Lakes Camp), the trail drops through a small boulder field, and there is one section that can require some minor rock-climbing moves to navigate. The most cautious method is to drop your pack down first so that you can use your hands to downclimb. Crossing the lake outlet requires crossing a logjam. Use caution.
