Dry Lake Observed Density 2023

In the winter and spring of 2023, seven transects were established to collect data at varying positions on the north and south facing slopes as well as the flat terrain. The spatial distribution of these transects were designed to capture changes in snow properties related to aspect and position on slope including the base, middle, and top of slopes. The flat terrain transect was taken by traversing a circle around the SNOTEL station whereas all other transects were ~20 m in length perpendicular to the fall line (i.e., parallel to slope contours). These data were collected approximately once every month from January to May, resulting in 5 survey dates. All transects included GPR data collected with surface-coupled, common offset GPR units pulled over the snow surface. Following the GPR, depth measurements were collected in the track of the GPR at 2-meter spacing. Snow pits were also dug when time allowed to estimate bulk snow density.
