Strong surface temperature gradients have started to facet the top few inches of the most recent snow. This snowflake began the faceting process around Dec. 27th and is likely now a full-fledged near-surface facet.
Surface hoar has also formed in many wind-protected areas at all elevations. Some of the largest feathers are more than an inch long. Here are a few close up photos taken Dec. 27th.
