Anticipate a layer of heavy, dense snow on the surface, overlaying lighter snow below, as a result of the recent storm that began with colder temperatures and ended with warmer conditions and potentially rain. Around 30 cm of recent snow has buried a widespread melt-freeze crust, possibly with a weak layer of surface hoar crystals resting between the crust and the new snow.
Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards at or just below the snow surface across all elevations.
