These are some example snowpack profiles for the Atwater site in Alta, Utah computed using the SLF's SNOWPACK simulation tool.

Flat Density Profile Today North Facing Slope Density Profile Today East Facing Slope Density Profile Today South Facing Slope Density Profile Today West Facing Slope Density Profile Today
Figure 1: Today's snowpack profiles for a flat slope, north-facing 35 degree slope (NF), east-facing 35 degree slope (EF), south-facing 35 degree slope (SF) and west-facing 35 degree slope (WF). Simulations are driven using data from the Alta Atwater Snowstudy Plot. Symbols: rFC - rounding facets, IF - ice formation, MF - Melt freeze, SH - surface hoar, DH - depth hoar, FC - faceted crystals, RG - rounded grains, DF - decomposing and fragmenting particles, PP - precipitation particles. Note that the time is in UTC. Local Utah time is UTC -7 hours.
