Lightning strike below tree line. North East aspect. 30 degree slope. HS 205. Got no results on the extended column test- (ECTX), as well as nothing on the compression test- (CTN). Deep tap test showed a failure 85cm down on our January 11th crust - DTM 20. Noted ice crystals and Surface hoar on failed layer. Lots of wind slab up high but found good skiing off of the ridge 10 meters below ridgetop.
