Conditions on the western slope of Mount Washington & Monroe are thin. Today the skies were clear with calm southwest winds and temperatures in the upper teens. On 12/30, 2-3 inches of new snow had accumulated below treeline on Mount Washington. Clear and cold skies overnight created perfect conditions for the formation of small surface hoar 0.5 to 1mm in size. The shallow snowpack below treeline is loose and granular, consisting mostly of facetted grains. Exposed terrain in the upper elevations on this aspect has been scoured by the prevailing winds. Drifted snow above the protection of trees is consolidated and confined to leeward terrain features and the lowest reaches of drainages. The upper bowls in Oakes Gulf also lack sufficient snow for skiing.
