Avalanche Problem 1: Normal Caution
  • Type ?

Snow coverage varies throughout the forecast area with few places possible for over the snow travel.  Areas along the Sierra Crest north of I-80 have around 1' of snow above 8500' on north aspects.  The Mt. Rose area has 1-2' of snow on north aspects above 9200'.  Walking will be required to access most of these areas with snow.

Snowpack structure mostly consists of faceted snow and a variety of crusts.  As the clear days and nights continue without significant storms, the snowpack will continue to facet and lose strength potentially setting up a future weak layer.  Expect changing conditions as storms begin to impact our forecast region. 

Many hazards exist in snow covered terrain including: exposed rocks, bushes, trees, firm snow crusts and ice.  Specialized equipment may be necessary to safely travel through these areas.

Get up to speed on your continuing education. There are lots of online opportunites. At the awareness end of the spectrum, the Know Before You Go video is a great primer or reminder of how a few simple ideas can greatly expand the margin of safety for travel in avalanche terrain. Avalanche Canada's micro site on the "Rescue at Cherry Bowl" launches Nov 5 and will likely be trend setting in modern avalanche education. For something snowmobile specific, check out the Throttle Decisions video series. For more technical skills specific info, the Forest Service National Avalanche Center's webpage is a well put together online tutorial, direct and to the point, especially helpful if you are short on time but want something meaningful. To delve even deeper, Avalanche Canada's Online Avalanche Course is very well put together, offering excellent text, photos, videos, and even some interactive exercises. There is something of interest for every level and type of winter backcountry traveler.
