Test profile dug prior to storm of nov 25th. Recieved 23 cm after profile dug. Repeated CTM 11, 11 SC dn 9. ECTN. No observed whomphing on <30 degree slopes post storm. A 20 cm storm slab formed after the storm, no significant propagation, however, we stayed on small test rolls so could not see its propensity for propagation on larger slopes.

Natural size 2 observed on Mt Mckirdy post storm. Immediate lee cross loaded feature in the alpine. Crown distinct from several kilometers away suggests it was quite deep. Could not see how far it ran. No other similar slopes showed natural activity.
