My group dug a pit at 11600ft on a SE-facing aspect at 15 degrees. Found 4F between ground and 20cm, 1F facets between 20 and 45cm. 4F between 45-50 and F between 50-70cm with recent storm snow. The compression test resulted in a sudden planar at 20cm on tap 21. ECT was not resultant (ECTX). 1F slab had very weak cohesion.
