Catherdral glades 1900m

First report ever so take it with a grain of salt... Cathedral glades today on a N NE aspects Up to 1950m. About a half foot of new snow and minimal wind. Temperature was around -2c. No signs of instability. We got fresh tracks on all our runs . snow pit ECT was between 30° and 35° on a small test slope. No results. ECTX even on on sheering the block with my shovel only a portion of the block came of in a non propagating way.
