Black Mountain

We set off we the objective of assessing 2 elements of the public bulletin: possible reactive wind slabs on northerly aspects at TL and the bond to Feb 3 crust. Both layers were significantly more reactive than anticipated at profile site. Soft small cornices indicated that recent local loading at TL had come form an Easterly wind so we chose a west facing 45 degree small open slope 5 m below a soft cornice. We found 33cm wind loaded upside down HST (top 27cm 1F/1F+ on 6 cm 4F) sitting on Feb 10 crust. HST produced ECTP3,4 (SP) down 27 on density change. No result on Feb 10 crust. Feb 3 crust was found down 70 at profile site and showed sings of breaking down. We got ECTP11,13 (SP) down 70 immediately under the crust.
