There are two layers of concern here: 1) a buried sun crust (on solar) and facets (on polar) down 20-40cm, and 2) a facet/depth hoar layer down 80-100cm that was buried mid season. These layers have become more active within the recent additional snow load, and are more prone to triggering during periods of intense solar radiation.
