Flathead Avalanche Center

Surface was re-thawed crust. Notable layer of crust down 8-9cm observed in profile was likely observed 3/15 slush layer. Unstable test results observed within facet layer below crust in snowpit tests. Highly variable frozen vertical percolation drainage tubes were also observed 9-20cm down within snowpack.

Slush layer observed 3/15 is observed in this profile as horizontal ice layer down 8-9cm. Highly variable frozen vertical percolation drainage tubes were also observed within snowpit.

We observed an ECTP with 2 additional taps at 109 cm, following an ECTX with the standard 30 taps.
