Mount St. Helens is OPEN during the government shutdown
For current information, please visit the link below.
Last update: November 3, 2025
What a difference a week makes! The Bivouac road is melted out and the summer route continues to be the best route to the summit.
Bivouac: The road is officially "closed" but the gates are reported to be open and this remains the easiest climbing route for now. There is almost no snow on the road and Bivouac. There may just be a trace of new snow on Monday and Monday night, but otherwise, it will rain on the Bivouac all week.
Marble Mtn: Snow free, but this is a much more challenging route (distance, terrain, and navigation) than the summer route, especially when there is very little snow. It will rain here all week.
Ski: Not enough snow yet except near the summit where conditions will be very icy.
Climbing: Bad weather, snow, whiteout conditions, and a lot of ice up high.
Summit Forecast:
- Monday 11/3: Stormy. Very cold with whiteout conditions and very difficult navigation. High winds (35+ mph), rain low down and then steady snowfall above the treeline, summit highs around 25 F. Lots of snow and ice on both routes, especially above 6000'.
- Tuesday 11/4: Light rain and snow. Summit temps around 30 F with winds to 25-30 mph. Clouds and fog with perhaps a break in mid-afternoon before the next storm moves in later in the day. Lots of snow and ice on both routes, especially above 6000'.
- Wednesday 11/5: Stormy. Very cold with whiteout conditions and very difficult navigation. High winds (45+ mph), rain low down and then steady heavy snowfall above the treeline, summit highs around 25 F. Lots of snow and ice on both routes, especially above 6000'.
- Thursday 11/6: Stormy. Cold with whiteout conditions and very difficult navigation. High winds (35+ mph), rain low down and snowfall above the treeline, summit highs around 25 F. Lots of snow and ice on both routes, especially above 6000'.
- Friday 11/7 into the weekend: The storm may continue into Friday and then taper off into the weekend, but forecasts differ. The Bivouac will remain the preferred route.
ROUTE INFORMATION
October 27: The summer summit route has 1-5' of snow. Excellent winter skills, climbing snowshoes and crampons are required. Deep snow and rime ice present difficult climbing conditions.
EXERCISE EXTREME CAUTION AT THE RIM. Portions of the rim are actively crumbling into the crater and there are sections that are undercut. These sections have been covered by ash and ice and are difficult to see. Stay back a few feet from the edge.

Air Quality at Mount St. Helens
The sensor that captures the data below is at the Science and Learning Center at Coldwater and is operated in partnership with Washington Department of Natural Resources. Conditions may be different at other locations throughout the Mount St. Helens area and at different elevations.
Roads
ROADS: At this time in the season, road conditions change daily. FS-83 and Marble Mountain Sno-Park parking areas may be wet, slushy, or snow-covered.
South side, October 30: Roads should be clear and passable until the next storm that has snow at lower elevations.
West side, October 30: Highway 504 is clear to the Science and Learning Center and down to the Hummocks trailhead.
East side: Windy Ridge, no recent reports.
October 31 FR 83 on the way to Lava Canyon
October 27: 830 road only passable with high clearance 4WD. No SUVs.
October 26 Slushy road at Marble Mountain Sno-Park
October 26 Slushy road at 81/830 intersection (road to Climber's Bivouac)
Climbing Route
CLIMBING ROUTE: Monitor Ridge Route, aka Summer Route from Climber's Bivouac. As of 10/14: summer route is still open. Forest is muddy. Expect snow above the treeline. Traction devices (microspikes or crampons) are required for safety. The boulders are beginning to be covered with ice and are difficult to traverse. Expect 12-16" of snow above 6000'.
CORNICE WARNING: Stay on the rim and do not step down onto the scree shelf just below rim.
NAVIGATION: Navigation is essential as well-worn paths above the treeline are covered with snow. Come prepared to navigate your path.
Cornice
CORNICE WARNING: The rim cornice has melted out, but the rim edge is fragile and sloughs regularly. STAY BACK - STAY ALIVE.
Avalanche Conditions
AVALANCHE CONDITIONS: NWAC Avalanche foreasting has concluded for the '24/'25 season. It is your responsibility to decide when, where and how to travel. Make sure you have the experience and skills to evaluate avalanche danger, and match your terrain choices to the conditions. Give the highest priority to observations of recent avalanches and other signs of instability, such as shooting cracks, rollerballs, significant snowfall/wind loading and rapid or prolonged warming.
During avalanche season, regularly check the Northwest Avalanche Center for up to date information.
BE PREPARED
BE PREPARED: Know the types and uses of traction devices, ice ax, and self-arrest techniques. Know the forecast at all elevations before your climb, have cold/wet weather layers and redundant navigational aides (map, compass and GPS) for low-visibility conditions. Have GPS basemaps and tracks in your navigation device before you go and look for pole cairns that mark the route above treeline.
PERMITTING: Washington Sno-Park Permit required as of Dec 1. Refer to the recreation and permitting site for current permit dates, prices and limitations. Information about Washington State sno-park passes can be found here.
CLIMBING ROUTE: Refer to the recreation and permitting site for current permit dates, prices and limitations. Climbing information from the Mount St. Helens Institute is found here.
LEAVE NO TRACE: Climbers are required to utilize blue bags to pack out all human or pet waste, including toilet paper.
CAMPING: There is dispersed camping and pit toilets available at the trailhead, but no running water, and bathroom services may be limited so please bring your own toilet paper, soap, water, or hand sanitizer. Please plan accordingly.
