HS on northerly aspects BTL ranged from 130-165. Boot pen 50cm and 20cm ski pen. Facets ranged from 40-60cm from the ground and is still primary area of concern. WL also sits 45-65cm down from surface with shovel shear tests and one CT test on 1/27 producing results, with 2 CT's on 1/26 no producing reaction and stepping below to 55cm facet layer. ECT tests continue to produce no results on 1/26, but PST on 1/27 shows 43/100 (Arr) at 55cm problem area. While skiing no cracking or collapsing noted on E aspects and N aspects below treeline in sheltered areas. Bridge feels there walking around and pole plants but should not be trusted fully until more storms come in.
