surface hoar's primarily a maritime issue, that's why last year was so anomalous. usually when it's clear and calm here it's so dry that there's not enough moisture in the air to form surface hoar, while it's obviously abundant in coastal ranges. correct me if i'm wrong but that's my understanding.

Makes sense to me. And some years there is considerable overlap between the regions (Maritime, intermountain, continental). I'm sure one of the pro avy dudes/chicas can chime in.
I think it also helps that many N. Utah storms come in warm, wet and windy. Sun and wind help destroy surface hoar. Warm snow helps bonding. It's those dark, hidden, wind protected N. facing open slopes that can keep the surface hoar there when a new storm comes in. Tree run right next to a slope like this might not have the buried surface hoar....pockety.

By analyzing local meteorological data, we confirm that low to moderate wind speed, humid air, and clear-sky nights are the necessary ingredients for the occurrence of significant vapor fluxes toward the surface and thus for the growth of surface hoar.

Surface hoar forms when there is a temperture gradient between the snow and the air. Snow warms in the sun during the day, gets moist, it get cold and clear and then that moisture moves to the surface to create the hoar frost. In other words, Utah is a great climate for surface hoar, you see it form during most periods of high pressure.

That's what we call surface hoar around here, and I always thought it was surface hoar, but then I remember some sort of event with moist air last year that the UAC was referring to as surface hoar (or maybe they called it hoar frost). It was nasty and persistent. I can't remember the exact cause, but I do remember hearing that it was more common in maritime climates. I think that the stuff we call surface hoar is really more properly referred to as faceted snow.
Anyway, your both right, or wrong. Whatever.

HOAR
having toured a ton in the wasatch and the high peaks of nh (maritime), i must say that i've skied epic surface hoar in utah and none i can think of in nh.
when the weather goes high n dry for weeks at a time with clear cold nights the wasatch gets deeper and deeper with it. i swear some of my best touring days in utah have been 2 weeks into a high pressure when most folks got fed up and lost interest and the hoar just got deeper and deeper.
up high in nh, we tend to get so many small snow/wind events that we don't ever really grow the stuff.
mmmmmmmm flaky potatoe chip skiing, mmmmmmmmmm.
