Snow pillow

A snow pillow is a device for measuring snowpack, especially for automated reporting stations such as SNOTEL.

The snow pillow measures the water equivalent of the snow pack based on hydrostatic pressure created by overlying snow. Any discrepancy due to bridging is minimized by the large dimension of the pillow, typically 3 metres (120 in) square.
