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.

CLIMBING ROUTE INFORMATION
The Monitor Ridge Route out of Climbers Bivouac is now the preferred climbing route to summit Mount St. Helens. Currently, it is possible to climb to the summit along a largely snow-free route. From the Crater Rim to ~6000' there are several established glissade chutes, but climbers are advised that there are rocks, bare spots, and other hazards to be aware of. Some chutes trend West and off-route - know where you are going before committing to a chute if you are attempting to glissade! Be advised that this weekend a storm is expected to bring ice and snow to the upper mountain.
EXERCISE EXTREME CAUTION AT THE RIM. The cornice is present and dangerous. Marker wands have been placed to identify and delineate the safe area adn the unsupported overhanging cornice. Currently, the cornice blocks the view from the crater rim at the top of Monitor Ridge, but ~300yards to the west views of the crater can be had safely. Do not approach the unsupported edge of the rim! Stay back - stay alive!
