Snowpack Observations


Various fog layers lingered below 7,000 feet, clear skies above during a tour in Avalanche Gulch. We have received two inches of fresh snow out of the past micro storm arriving yesterday between 4 a.m. and 7 p.m.  (20200122). This fresh sits over an icy and consolidated brick of a snowpack. Before this storm, warm temperatures and periods of strong north and west wind have left a scored, shallow and rocky patchwork above treeline. 

The fresh snow barely hides many rocks. Today, air temperatures stayed slightly below freezing and maxing out at 31.5 F at 2 p.m. at our weather station in Old Ski Bowl.  The snow depth is 40 inches (101 cm). Winds were calm to light and variable in direction. No obvious signs of avalanche danger were observed. Anticipated changing conditions as we receive more snow.
