Snowpack Observations


Today Sam and I completed a snow survey in the Eddy mountains. After this, we gathered observations during a tour on a northeast aspect around 6,800 feet. The weather behavior was inconsistent and variable to say the least. Partly sunny skies and good visibility would turn to blowing snow and bad visibility in the blink of an eye. A moderate south-southeast wind near and below treeline transported snow over ridge tops, across gullies, and refilled skin tracks over a one-hour period. Apart from wind exposed areas, the snow we encountered was undisturbed and low density. A pulse of moderate snowfall lasting roughly 30 minutes began around 2 pm, delivering a mix of precipitation particles in the form of rimed stellar dendrites and graupel. A 155 cm snow pit displayed a well bonded right-side up snowpack structure. A CT test initiated a fracture in the top 20 cm of the snowpack on the March 4th and 5th graupel interface. No other test results, or signs of instabilities were observed.
