Snow pits are dug during winter to investigate the layers and properties of snow within a snowpack. Nearly 50 snow pits were dug during the winter observation period for this study to help understand how snow settles, forms layers, and morphs as the season progresses and more snow falls.

Number deployed on SOS Project: 48
