No red flags noted; ski cut some steeper test slopes with no results; a bit surprised to get ECTP17 times 3 on a north facing slope at 9500'; failing on - "mixed forms" beneath a thin thermal crust. At 9000', I could not replicate the results. My sense is that this is just a "structural irregularity" that does not jive with general avalanche conditions but should be something to be aware of.
