Good morning, this is Bruce
Tremper with the
The 4-7 inches of light snow that fell on Sunday and Sunday night gave the snow a well-needed freshening up.† Turning and riding conditions were actually quite nice yesterday if you knew where to look.† The hot tip today is to stay on gentle slopes 15-25 degrees, out of the wind and sun and on upper elevation slopes that already have a base layer.† Yesterday, it was a chilly face mask and keep-your-hood-on day up on the ridges in a stiff east wind with temperatures in the single digits.† Despite the cold temperatures yesterday, the sun crusted up the new snow on the southwest through southeast facing slopes.† But overnight, some high clouds have streamed in from the north and ridge top temperatures have risen up into the 20ís.† Winds are generally light from the north.
The stiff winds yesterday from the east and northeast created some pockets of fresh, soft and mostly shallow wind slabs along the ridges, mostly on south and west facing slopes and the winds occasionally dipped down off the ridges as well.† I was able to intentionally kick off several sensitive, shallow, soft slabs yesterday as I traveled along the upper elevation ridges.† These were generally less than a foot deep and quite soft, so they were not particularly dangerous unless they were on a slope with bad consequences.† There were also a few damp sluffs yesterday as the new snow heated up in the sun.† For the most part, the new snow doesnít weigh enough to cause deeper, larger avalanches breaking into old snow and today the main danger will be from the fresh wind slabs.† We may also have a few damp sluffs on the steep sun exposed slopes again today.
Bottom Line (SLC,
The avalanche danger today LOW except for pocket of MODERATE danger on any slope steeper than about 35 degrees with recent deposits of wind drifted snow.
Today we should have variable
high clouds with ridge top winds from the north around 10 mph and ridge top
temperatures around 20-25 degrees.† 8,000í
temperatures should rise up to near 30 with overnight lows around 12.† The storm that pushed through on Sunday has

UDOT in Little Cottonwood Canyon will be sighting in the cannons on Wednesday morning and shooting from Tanners through Superior from 7-8 am.† The road will be closed while they do this and it would not be a good idea to do a dawn patrol on those slopes on Wednesday morning.
A great Christmas present
this year for someone you love would be an avalanche beacon.† If you want to know which one to buy, Iíve
posted a couple recent tests of various brands of avalanche beacons on the web.
