Highlights

Today the avalanche danger is CONSIDERABLE. Human triggered avalanches are LIKELY on steep slopes with recent deposits of wind drifted snow near treeline and above that face NW-N-NE-E. In some areas, thick slabs of drifted snow exist over buried weak layers where you can trigger a deeper and more dangerous avalanche. Avoid steep, wind loaded, northerly aspects. Shifting winds will create shallow, soft slabs of wind drifted snow on Southerly facing slopes where you will find a MODERATE danger.

    Blowing and drifting of the new snow has created fresh, unstable slabs of wind drifted snow near treeline and above. The deepest most dangerous drifts will be primarily found above treeline on slopes that face NW-N-NE-E. These drifts will be up to two feet deep and will be sensitive to the weight of a skier or rider. North winds will bump up just enough today that shallow drifts will start forming on Southerly facing slopes as well.

    Drifted snow is stiffer and more compacted than non-drifted snow, and hard drifts often produce hollow drum-like sounds when you walk on them. Shooting cracks in drifted snow are a sure sign of instability. Avoid slopes steeper than 30 degrees with recent deposits of wind drifted snow.

    On some northerly aspects, wind drifted snow is sitting on top of buried weak layers. A layer of weak faceted snow formed on the surface early this month and it was covered by a foot of snow on Valentines day. It isn't widespread, and it hasn't proven to be very reactive in stability tests, but it's out there. A weak interface also exists at the bottom of last week's storm snow. The few avalanches that ran on Saturday likely failed on one of these weak layers. The most recent round of fresh wind drifts will add stress to these buried weak layers, steep terrain should be avoided until we see how they react to the new load.

Special Announcement

Geyser Pass Road: The Geyser Pass Road will be closed this morning for plowing. Expect it to be closed until early afternoon.

Grooming: Trails were last groomed on Saturday and will covered in fresh snow today.

Weather

It is a cold morning in Gold Basin as the low exits our area. We can expect sunny skies today with a high around 18 degrees and cold North winds blowing in the 15-20 mph range. We will have cold, breezy, and clear conditions through the weekend.

General Conditions

Skiing conditions should be great today with an 11 inch storm total. Relentless Southerly winds have finally backed off and shifted to the North. You'll want to seek sheltered terrain for the best skiing and riding conditions. Fresh unstable slabs of wind drifted snow exist near treeline and above. Be on the lookout for signs of instability such as cracking in the snow surface. On northerly aspects near and above treeline, thick slabs of drifted snow exist over older, weaker layers. For now, I am avoiding steep Northerly facing slopes until I see how these weak layers react to the recent storm.

Additional Info

Are you wondering how cell phones and other electronic devices can interfere with your avalanche transceiver? The "20/50 Rule" is that you want your beacon 20cm (8") away from other electronics while transmitting and 50cm (20") away from electronics while searching. Get the full scoop here.
