I'm the high exposed terrain this is a lot of wind loaded slopes (added weight) on easterly through northerly slopes.

We saw a small slide on a east facing aspect at around 8400ft (see pics below) with the added wind loading from recent storms combined with the spring heat this could be problematic moving fwd.

Comments
We dug a pit on a North by Northwest facing aspect at about 8400ft. Though we did not get propagation with our ECT (Exteneded column test ECTX) we found two worrisome weak layers. One at 30 cm's from the surface (graupel see first pic) and another at about 100 cm's which appeared to be some light faceting (see second pic) both broke with a clean shear with pressure from the shovel. The snow surface is/was very wet, dense and heavy which could lead into wet avalanches. It's April, the sun is high, and most aspects are now getting sunlight and warmth. Use caution!
