Current Conditions
Mount St. Helens Climbing Route
Safe backcountry travel requires preparation and planning. Current Condition information listed here is collected from on-site observations, multiple state and federal sources, and presented for recreational purposes. This is only one component in a spectrum of critical preparation and should be combined with current weather and avalanche forecasting at all elevations, advanced alpine education, fitness training, proper equipment and attire, and the "Ten Essentials." Mountain conditions are dynamic and can change rapidly without warning. Winter conditions can exist from October to July.
The user acknowledges that it is impossible to predict natural events in every instance accurately, and that the accuracy or reliability of the information provided here is not guaranteed. This report expires 24 hours after the posted time unless noted otherwise.
Last update: November 12, 2026
Climber's Bivouac: The Bivouac is currently free of snow. Be advised that the unpaved section of the road to the trailhead is degrading rapidly and is quite rough.
Marble Mountain: The Monitor Ridge route from the Climber's Bivouac is still the preferred summit route until more snow accumulates along the Worm Flows route.
Climb: Right now, there is no snow below 6.000'. The boulder sections of the route are full of fragile snow bridges due to the recent precipitation. The upper mountain, especially above 7900' has hard ice over snow on the route. Traction aids like microspikes or crampons and an ice ax are needed. Inclement weather and resulting conditions require careful consideration if planning an outing in the coming days.
Summit Forecast:
Thursday 11/12: High clouds. Windy (20-30 mph). A high of 37*F on the rim.
Friday 11/13: VERY COLD with winds to 45 mph and a summit high of 23*F. Rain below 6,000' and several inches of snow up higher. Anticipate dense fog and whiteout conditions.
Saturday 11/14: VERY COLD with winds to 40 mph and a summit high of 25*F. Rain below 6,000' and several inches of snow up higher. Anticipate dense fog and whiteout conditions.
Sunday 11/15: VERY COLD with winds to 40 mph and a summit high of 21*F. Rain below 5,000' and 6-10" of snow up higher. Anticipate dense fog and whiteout conditions.
Monday 11/16: VERY COLD with winds to 30 mph and a summit high of 19*F. Rain below 4,000' and light snow up higher. Anticipate dense fog and whiteout conditions.
Tuesday 11/17 into next week: Light rain and snow, wind, some sunshine, but periods of fog.
CLIMBING ROUTE INFORMATION
From the Northwest Avalanche Center:
When it comes to early-season avalanches, the bottom line is simple: if there’s enough snow to ride, there’s enough snow to slide. Whether you’re out hiking, hunting, searching for some early-season turns, or breaking out the snowmobile, don’t let the date on the calendar fool you. Avalanche accidents and fatalities have occurred this time of year.
Limited information makes it tricky to determine when and where you might trigger an avalanche. Often, the same places we seek out for early-season fun are the exact locations where avalanches are more likely:
- High elevation terrain
- Permanent snowfields
- Wind drifted slopes
Be cautious in terrain where snow hides vegetation and rocks. As snow depth increases, so could the size of avalanches. You’re most likely to encounter unstable snow:
- During and immediately after a storm
- In steep, wind-loaded terrain
Even though the amount of snow on the ground may limit the size of an avalanche, terrain traps can cause even tiny slides to result in serious injury or death. Avalanche fatalities have occurred from a victim being:
EXERCISE EXTREME CAUTION AT THE RIM. Do not approach the unsupported edge of the rim! Stay back - stay alive!

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.
