January 29, 2017 update

Road to Climber's Bivouac is closed due to accumulating snow.  The winter climbing route (worm flows) out of Marble Mountain Sno-Park is now the preferred climbing route until spring. However, FR 83 is only open to Cougar Sno-Park at the current time. 

The snow level is currently at right around 1,500'. 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.
