Snowpack Observations


A wildly windy day with whiteout conditions at times. Took an afternoon snowmobile tour up Parks Creek road to 6,500 feet.  FS road 27 unplowed, was able to drive 1.4 miles up to first major switchback to park, wouldn't recommend it as more snow accumulates. Snow fell all day with strong SW wind. Wind effect on the snowpack was evident near and above treeline. Snow accumulation was rapid, greater than 1 inch per hour at times. An average of 30-45 inches of snow (HS) was measured at 6,500 feet. Wind drifts were encountered 6-7 feet deep. The entire snowpack in the Eddies is fist to four finger hardness. I stepped off my snowmobile and sunk to the ground. Visibility and travel in the backcountry very difficult. Unable to access any other terrain, but avalanche hazard was considerable to high.

The Eddies snowpack is ripe for blasting an A-arm on a snowmobile or taking a stump to the leg. Be careful. Prior to this storm, the snowpack was little to none. Give the snow a little time to settle, both for avalanche concerns and hidden obstacles to hibernate.
