It's anybodies guess how much snowfall we recieved last weekend! In some spots it was blown down to the ice crust and in other areas the drifts are four feet deep. Watch for areas where the snow has been drifted into pockets. Steep chutes, gullies, steep rolls and wind-lips, not to mention shallow depressions below ridgeline; these are the spots to watch, any areas where the snow was deposited by the wind and the terrain is steep! In the coming days this week the sun will be out, any aspects taking on the afternoon sun will be a little more prone to cutting lose under the weight of a sled or rider.

It's going to be a beautiful week and the sun will shine. Watch your exposure the next couple of days as the afternoon sun will heat up steep slopes that are now loaded with fresh snow. Expect to see some "loose-wet" avalanches on the hill as things heat up. As always, pay attention to whats below you and try to avoid high consequence areas (terrain above cliffs and timber) once the surface snow starts to show signs of instability such as pinwheels and rollerballs.
advisory discussion
Life is a little dynamic right now. Corona Virus is on the rise and stocks are crashing. Yin and Yang. You may or may not be concerned about either! If you are me, you just think about what the snow is like all the time (and maybe having a couple extra rolls of toilet paper on hand). As mentioned, my time to poke into the mountains and dig in the snow will be a little limited for the rest of the month. Advisories will continue to go out first thing Friday mornings and conclude on March 27th. I will still issue some info on Monday evenings or Tuesday mornings for those of you who plan to go out early in the week. In the meantime, keep a level head and enjoy that sunshine!

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.
