CURRENT CONDITIONS

May 17, 2017 update

Road to Climber's Bivouac is still closed due to snow. It is unlikely to open before mid-June. The winter climbing route (worm flows) out of Marble Mountain Sno-Park is the preferred climbing route until spring. There is no parking fee/Northwest Forest Pass needed at Marble Mountain Snopark. Dispersed camping is avaiable in the vicinity of the parking lot.

The snow level is currently at right around 2,800' with well over 120" of snow at 3,400'. Please check the forecast as weather conditions are very variable at this time of year. It is wise to be prepared for cold, wet, winter conditions by having appropriate winter climbing gear and strong winter navigational/orienteering/mountaineering skills.

See the U.S. Forest Service Mount St. Helens National Volcanic Monument website for more information.
