Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Thursday - March 29, 2018 - 6:57am
bottom line

Areas of isolated or MODERATE danger still exist on steep, wind drifted slopes right around treeline and above that face NW-N-E where it may be possible to trigger a deep persistent slab avalanche up to 4' deep, particularly in areas of rocky or more radical terrain. Steep wooded areas are also suspect. Choose slopes wisely and avoid steep convexities and blind break-overs.

Most other terrain in the La Sals currently offers LOW danger.

Episode 7 of the UAC Podcast "Mastery and False Mastery - An Interview with 'Big' Don Sharaf" is live. With a snow career spanning over 30 years, Don has enough mileage in the mountains to have learned a thing or two, including the profound value of humility when staring into the face of the dragon. Listen in on our conversation about the idea of mastery and if such a thing can exist in the avalanche world. Check it out on ​the UAC blog, ITunes, Stitcher, or wherever you get your podcasts.

The UAC Marketplace is still open. Our online marketplace still has deals on skis, packs, airbag packs, beacons, snowshoes, soft goods and much more.

There isn't much snow available for transport, but there may be some isolated fresh wind drifts formed by the strong NW winds, or a few old hard wind slabs about. Suspect smooth rounded deposits of wind drifted snow, or areas that have a hollow sound or feel to them. Even a small wind slab triggered in areas of more extreme terrain could sweep you off your feet and take you for a ride over a cliff.

We've entered the low probability - high consesquence phase with our persistent slab problem. Weak snow still exists right around treeline and above on slopes that face NW-N-E and it may still be possible to trigger an avalanche up to 4' deep in these areas. Slopes with an easterly component are the most suspect, as are areas of rocky and more radical terrain. Choose slopes wisely and be leary of steep convexities and blind breakovers.
