Blog: Practicing Companion Rescue - Dec 10, 2017 - Toby Weed
We need to practice Companion Rescue techniques often, and with all our backcountry partners.  With a persistent high pressure and shallow snow in the Utah mountains, now is a good time to do this.  You can practice anywhere. All you need is your gear, a partner or two, and enough snow to bury a pack.  For more information and to learn directly from the experts, go to our our Classes and Workshops page for listing of our Companion Rescue Fundamentals classes.....HERE


Blog: Adjusting to a Different Snowpack Climate - Nov 5, 2017 - Guest Blogger Tyler Falk
[This blog entry is provided by pro UAC observer Tyler Falk. Tyler presented this work at the Utah Snow and Avalanche Workshop on November 4, and it is also scheduled for publication in the December issue of "Avalanche Review" which is published by the American Avalanche Association.] Adjusting to a Different Snowpack Climate The 2016/2017 winter season in the Salt Lake area mountains will be remembered by many to have felt overall warmer and wetter than normal. Some might even call it coastal, based on our weather and avalanche activity. I recently looked at all the available data on...

Blog: Week in Review (April 8-14) - Apr 14, 2017 - Greg Gagne
Week in Review [April 8 - 14] A storm system entered the region this past weekend, with warm temperatures and a high rain/snow line on Saturday April 8th. A cold front with an ample moisture supply late Saturday night and well into the day on Sunday provided nearly 18-24" in the Cottonwoods and Ogden mountains, with 8-15" along the Park City ridgeline. The Provo mountains recorded 3-6". Limited avalanche activity was reported with this storm, with a few slides breaking at a graupel interface of the old snow surface, or within a density inversion within the storm snow: [Mark...


Blog: Week in Review (Mar 31 - Apr 7) - Apr 7, 2017 - Greg Gagne
On Thursday March 30 the central Wasatch received about 6" of storm snow. On Friday March 31, sun and greenhousing crusted all aspects and elevations, with the exception being northerly aspects above 10,500'. A round of significant wet activity occurred by mid-afternoon Friday:   Saturday brought a clear and warm day, and another round of loose, wet activity followed as the northeast winds began to relax.     On Sunday, a weak storm system deposited 1-4" at the upper elevations which improved riding conditions. Monday through Thursday was highlighted...


Blog: Week in Review (Mar 24-31) - Mar 31, 2017 - Greg Gagne
This past week has been highlighted by the see-sawing of storm and bluebird days, with avalanche activity ranging from storm and wind slabs during stormy periods, to predictable wet activity on sunny days. A weak storm on Saturday delivered 4-6" by late in the day in the central Wasatch. Sunday started cool & clear, but the strong March sun brought the usual round of shallow wet loose activity by mid-day. Monday was a classic March storm, with snow totals ranging from 6-13" during the day. A particular highlight was Alta recording 7" of snow from noon - 1 pm. Jim...


Blog: Week in Review (March 17-24) - Mar 24, 2017 - Gagne
The prolonged ridge of high pressure (aka the "Dylan Ridge") continued through the weekend of March 18/19 with breezy conditions ahead of a week system that produced a few mountain rain showers and a trace of graupel on Monday. Skies cleared somewhat later Tuesday, and Wednesday brought a warm, moist storm system that deposited up to 5" of dense graupel, with 20% density. The rain/snow line was above 9500' During this past week, many mountain locations maintained above freezing temperatures for well over a week. On Thursday a moist storm system arrived, bringing the first...


Blog: The Little Things (that might keep you alive) Part 4 - Mar 22, 2017 - Tom Diegel, Guest Blogger
“It’s long been an axiom of mine that the little things are infinitely the most important” – Sir Arthur Conan Doyle While the last week or two has felt an awful lot like spring, there is no doubt that we’ll be getting additional storms before the sun comes out in earnest.  Typically the snowpack gets more stable in the spring, but we’ll hopefully get enough snow that avalanche danger will again rear its head, and we’ll need to respond accordingly.  Along those lines, here is the last of The Little Things that might help to keep you safe in...


Blog: Week in Review (Mar 10-17) - Mar 17, 2017 - Greg Gagne
Week in Review - Greg Gagne The past week has been highlighted by what hasn't happened, which is any resemblance of winter. The most dominant ridging pattern of the otherwise excellent 2016/17 winter season has placed a stranglehold on the Wasatch. High and low temperatures observed this week at Alta guard station at 8800' in Little Cottonwood Canyon: Saturday 3/11 46/28 Sunday 3/12 40/29 Monday 3/13 50/29 Tuesday 3/14 52/33 Wednesday 3/15 54/37 Thursday 3/16 51/34 As can be seen, it has been several days without below freezing temperatures. Other stations recorded much...


Blog: The Little Things - habits that might keep you alive Part 3 - Mar 13, 2017 - Tom Diegel, Guest Blogger
This installment of “The Little Things” associated with safety involves the most difficult component of skiing in avalanche terrain:  ourselves!  One thing that my partners and I like to do is maintain good backcountry habits; we do this to avoid getting surprised and to be prepared for that rare incident that can change your day from fun to terror.  Be sure to check out installments one and two.  And look for number four in a few days! Any pilot will tell you that following protocol is a good way to improve the odds of a safe journey, regardless of conditions...


Blog: Week in Review (Mar 3 - 9) - Mar 9, 2017 - Greg Gagne
The weekend of March 4/5 was highlighted by increasingly strong winds, with upper elevation gusts over 70 mph at many mid and upper elevation stations. These winds were ahead of a vigorous cold front that hit the Wasatch mountains early Sunday evening, where some even heard the sound of a thunder as it roared out a warning of the approaching storm. For those that did not seek shelter from the storm, by Tuesday morning they would have found storm totals including 11-16” in the Ogden, Park City and Salt Lake mountains. (Significantly less snow fell in the Provo mountains where 2-3"...
