ECTP 28 in the N. Gallatin

Snow bikers in the northern Gallatin Range found unstable test results on the early December facet layer (12/30). "While snow biking... We dug a snow pit at 9100 ft elevation & discovered a weak layer that propagated at 28 on the ECT test about 18 inches down. The snow below that area was all loosely faceted."
