Freeskiguy, a gut feel is that although these west and south facing gullies (as in the first of your last four photos) would slide with new snow instabilities they are probably unlikely to go as depth hoar slides until springtime when the faceted snowpack becomes very weak and isothermal. The gut feel is just based on the width of the starting zones and the amount of lateral anchorage in the gullies.

One sceinario that might produce a ground hoar avalanche in this coulairs(the Big K pic above) would be low depth early season lingering snowpack, cold clear weather for a while (Attic air mass) and then some heavy snow loading.
