Comment:
This dataset is of numerous snow pits that were dug in the spring of 2015 in the Dry Lake study site in northern Colorado. Within each pit measurements were taken for snow depth, snow density, and soil moisture content directly beneath the working face of the pit. Snow density was measured using a snow tube to obtain a single core that was then placed in a bucket and measured for mass and depth was measured using markings on the snow tube to the nearest centimeter. Soil moisture was measured using a handheld TDR for volumetric water content. Volumetric soil samples were taken from test locations for lab confirmation and calibration of field measured data. Location are UTM coordinates in UTM 13N NAD83 datum.
