Snowpit #2 Conclusuions: Examining the data regarding Snow Pit 2 from the Northwood School we observed that the snow was visibly stratified into five layers. This number of layers was confirmed by the finger test. The density of each layer increased with depth as might be anticipated in a late season snow pit. The temperature approached zero Celsius as the depth increased to the ground-snow interface. There were five distinct layers evidenced in the snow pit, indicative of 5 seasonal snow/precipitation episodes. |
