Quick report

Great skiing and great coverage at Nadahini. Dense powder skied well in the gullies and bushes. We were skeptical of stability with all the new snow but structure and bonding between layers appears to be good for now. Will make a good base. No danger signs observed, other than wind loading and a fresh glide avalanche.
