No climbing route reports or photos since 11/10. FS-83 road to Marble Mountain Sno-Park is deeply rutted single track in 1 - 2 feet (30 - 61 cm) of snow on road surface. Plowing operations commence in the first week of December. SNOTEL stations report snow depth is 21 inches (53 cm) at 3,440 feet (1,048 m) and 5.1 feet (1.6 m) at 4,440 feet (1,353 m). MSHI volunteers have observed 12 inches (30 cm) of snow on forest roads as low as 2,800 feet (853 m). If travel to the area is critical, a high-clearance 4x4 or AWD vehicles with traction tires is required.
CLIMBING ROUTE: Winter Route, aka "Worm Flows" Route, Marble Mountain Sno-Park. The Summer Route and Climber's Bivouac are CLOSED. Traction devices such as Microspikes, crampons and/or snowshoes recommended for the entire route as new snow accumulates and settles. Avalanches possible, so avoid Eastern wind-loaded slopes. The cornice now overhangs the rim 8 - 10 feet (2.4 - 3 m). There are currently NO warning flags on the rim, so STAY BACK 30 feet (9 m) from the visible edge.
BE PREPARED: 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. Information about Washington State sno-park passes can be found here.
