North Gallatin Observation

Our group skied into the basin to the north of The Mummy in Hyalite on Saturday. Through the cliffs and bottom gully of the basin we noted stable cold snow with natural sluff coming from cliff faces and trees above us seeing warm sun for the first time in the week. At the bottom of the couloir we got an ECTX with total snow depth of 210cm. With a couple extra hard whacks with two fists after the test I did manage to get it to propagate @114cm. We performed a two different PST's in the upper snowpack at density changes and got PST 78/100 (End) @145cm and PST 67/100 (Arr) @ 166cm.

As we climbed the couloir a wind slab developed which eventually caused us to turn back at just over 9,000'. The wind slab was present on pretty much all aspects and edges of the couloir. Let me know if you have any other questions.
