Amazing tree skiing yesterday, even the kids were happy with the foolish amounts of snow.

At 2280 meters the temperature was -8 as of 06:00 hrs. Winds were 45-65 KPH from the S. At 1550 meters the temperature was -5, 99 % relative humidity, the barometer is dropping. At cat skinner weather plot 1 cm of new snow was recorded, at 1650 meters on Whistler 1 cm of new snow was recorded as of 05:30.  In the valley it is -0. Mother nature certainly had a different outlook than the forecast from yesterday!!!  The storm is still on its way with less snowfall than expected but the winds will certainly pick up as the storm moves in.

Winter has returned but when the sun does come out it is very strong, same strength as it would have in September. Cornices are still an issue as all this new snow helps them grow, several stories in the past week about cornice encounters, be aware. Here is a clip of a cornice failing on Whistler Mountain last week: Piccolo

Switzerland has some amazing terrain, Andermatt is one location where they are spending as much money as the Jumbo developers to create a resort like WhistlerBlackcomb, here is a great clip of some free ride skiing in that area: Good Footage


Not much information but there was an Avalanche at Panorama resort yesterday: Panorama

Using kids addition 391 cm of snow fell at 1550 meters at the Catskinner plot March 2012


The popcorn at the alpine shop was especially good!! Good incentive for child labour.

At 2280 meters the temperature was - 8, winds were 20-30 KPH from the SSE as of 06:00. At 1550 meters the temperature was - 5, 97% relative humidity, and the barometer was on the rise. At that elevation 13 cm fell over night and 11 cm fell at Pig alley. In the valley it is 0.

March was amazing, just over 5 m of total snow for the month, depending where you are in the corridor. Now that April is here it does not want to quit, further  possible accumulations of around 75 cm by Tuesday Morning.

Yesterday in the corridor numerous size 1-2.5 avalanches occurred, bigger occurrences were in the Duffy area.

Big Back Flip

Summary from Steep Creek

  • Valentine days surface hoar pwl is still active.
  • Can be triggered off shallow rocky start zones
  • To illustrate variability;  in ridge on the background, on slopes of similar N aspect with similar slope angles, cornice drops resulted in nil results.
Trigger stood in a convenient location to capture the skier about to drop into mini-Heartstrings. As he made the last step down to the shooting platform, the entire slope depicted failed to ground, carrying trees and stripping boulders and washing them downslope. The shooting cracks show that the failure initiated on Trigger's last step. The marks at picture top are where the skier crawled on his belly while thinking light thoughts and grovelled back to the "safe zone" where Trigger is standing.

The rocks in the near foreground used to be covered in snow but are obviously now uncovered. They are a classic shallow rocky start zone. None of us were terribly interested in a closer look at the aftermath but our suspicions are failure on the V-Day layer


Slope is N facing slope about 38 - 40 deg steep at 2100 m at location in Central Duffey.   
We found that the slide had zippered down from Trigger's shooting platform, had grown in size and further ripped to ground downslope entraining our skintrack and depositing rather large blocks of snow, uprooted trees and various size boulders on what was once perfectly good powder. It looks like this sympathetic release had crown sizes of between 1.5 to 2m. It too failed on the V-day layer (decomposing surface hoar of approx 1mm grains)




Taken from across the valley looking SE towards the slope in question

Thanks Erik
Yesterdays action Wayne
>
> Crowns down 20-60 cm, 50-200m wide, 50-200m long, east to west including north aspect start zones. Most start zones had a crust and some stiffness in the snow on that crust, suspect had small surface hoar on cr. To make it such a widespread weakness. Start zones were convex rolls at least 40 degrees. Na, sz 2-2.5 in Rutherford

Large climax slide off Wedge, May 1969.  Thanks to Cliff Jennings for submitting history.


Wayne,
Finally found the image. Taken in May of 1969. The helicopter pilot went through Wedge Pass in late September & still saw a huge pile of snow & trees in the creek bed at about 1300 meters. The slides started at over 2300 meters, so ran about 1000 vertical meters.
Cliff


As of 06:00 the temperature at 2280 m was - 12, winds were 15-30 KPH from the NNE. At 1550 meters the temperature was - 9, 93 % relative humidity and the barometer is dropping. At that elevation 8 cm of new snow was recorded. at pig alley 6 cm was recorded. Int he valley it is -2. 


In the corridor yesterday avalanche occurrences were Xe, Xc, Sc, size 1-3, 20cm - 1 m crown lines. 


Snow is still in the forecast, looks like Sunday night will bring us another storm into Monday.

Brandywine area last week, natural slide on wind loaded feature.               Erik Graham Photo

As of 06:00 hrs the temperature at 2280 meters was - 8, winds were 25-40 KPH from the S. At 1550 meters the temperature was - 4.5, 97 % relative humidity and the barometer was rising. 15 cm of new snow fell over night there and 15 cm at pig alley. In the valley it is -1.

Avalanche control yesterday produced size 1-2 soft slabs in the corridor.  Be wary of the February 8 Th interface, certainly would produce size 3 and with this new snow the interface from March 24 Th certainly has some size 2 potential.

Spring has sprung but there is still lots of powder skiing to be had!!

At 2280 meters the temperature as of 06:00 was - 7, winds were 70-100 KPH from the S. Max gust there last night was 120 KPH.  At 1550 meters the temperature was -3.5, 99% relative humidity and the barometer is on the rise after hitting the bottom. . 31 cm of new snow was recorded there and 27 cm was recorded at pig alley. In the valley it is 0.

The snow yesterday was very reactive, size 1-2 soft slabs easily triggered, 10-50 cm. Today will not be much different.

Not sure if the Whistler Peak weather station is 100% but it is saying 10-35 KPH from the S. The ridge weather station there at 2000 m is saying 50-95 KPH from the E, with max gust of 120 KPH.

Yesterday 11:00 and still no tracks, Blackcomb Bowl looking very inviting. The skiing yesterday was amazing, not just because of the 25 cm but there were no crowds.

25 cm fell by 12:00 noon yesterday.

Certainly will not be getting this view for a few days.

At 2280 meters the temperature is -6 as of 06:00 hrs. Winds were 50-70 KPH from the ESE. Max gusts last night were 96 KPH.  At 1550 meters the temperature was -2, 98 % relative humidity and the barometer is steady. 11 cm was recorded there and 10 cm was recorded at pig alley.  In the valley it is +3.
The freezing level is at 1300 m but it is snowing at 1100 m. Fl should drop and snow should reach the valley.

Some approaching fronts are so well defined.

At 2280 meters the temperature as of 06:00 was -6, winds were 20-40 KPH from the ESE. At 1550 meters the temperature was - 3.5, 87 % relative humidity and the barometer is falling. A trace of new snow was recorded over night.  In the valley it is 0.

With the expected snow on its way it will make it interesting with a 5-10 cm MFC on solar aspects and a 2-10 cm pencil slab on other aspects.

Some information on La Nina:

La Nina is rapidly weakening. The cold anomalies in the central tropical Pacific are rapidly declining and some parts of the tropical eastern Pacific are now warmer than normal.   Predictive models suggest that La Nina will be over by the end of April.
Good news for us, hopefully we will get some nice weather this summer.

Will be a busy week end in the back country. Read the article below and reflect on what your experience level is and how much risk you are willing to accept.

Factors Contributing To Recreational Avalanche IncidentsThere are a number of common mistakes that many backcountry recreationists make that put them at increased risk of being involved in an avalanche accident. These include:
  • Poor trip preparation
  • Lack of knowledge of recognizing avalanche terrain
  • Inability to assess snow stability
  • Unskilled backcountry search and rescue techniques
The basics of these skills, however, can be learned through avalanche awareness courses or by traveling with experienced people, and then refined over successive winters.
Other sources of information available to backcountry travelers can be found from many sources including the Internet, guidebooks, maps, information centers, and people who have been in the area.
Increasing Chances of Survival Through Risk AvoidanceAvoiding putting yourself at risk plays a large part in eliminating as many factors as possible that contribute to avalanche incidents. To this end, understanding the causes of being caught in an avalanche and anticipating them before and during the trip need to be considered. Steps that can be taken to do this include:
  • Designating a leader to help ensure effective decision-making
  • Putting people at front of pack who are skilled at assessing snow stability or selecting routes
  • Ensuring that “back in the pack” people don’t simply follow the track, but pay attention to the terrain or snowpack
  • Don’t fall into the “blue-sky” attitude that draws recreationists to upper slopes where unstable snow can remain days or weeks after a storm
  • Don’t focus on being goal oriented even after learning of unfavorable conditions such as rain, heavy snowfall, drifting snow, 0° C temperatures and poor visibility
  • Knowing when you are tired so that fatigue doesn’t cloud judgment and narrow the margin of safety
  • Recognizing that a sense of “it won’t happen to me” invincibility can be fatal
It is important that experienced members of a group assume the lead in determining where, when and if to proceed on a backcountry trip. Taking the opportunity to get together during the trip for important decisions on assessing snow stability, the route, and possibly changing weather conditions is always advisable. Sometimes a quiet voice asking, “But why do we think that slope is stable?” can prompt a careful re-assessment of the situation and lead to a sound decision. Also, involving less experienced people in route selection and stability assessment contributes to the experience of every person in the group that will pay off on subsequent trips.

Its that time of the year, be wary of cornices breaking and solar aspects. With the nice weather and sunny skies forecasted for the weekend use caution out there!!

At 2280 meters the temperature was - 11 as of 06:00 hrs. The winds were 10-30 Kph from the SSE. At 1550 meters the temperature was -8, 88 % relative humidity and the barometer is rising. In the valley it is -4. 1 cm was recorded at pig alley 1 cm at cat skinner. Surface hoar has been growing for the past couple of days.

Hi Wayne,
In case this is still of interest here are a couple of pictures taken yesterday of last week's Shuksan Arm avalanche (with 6 days new snow on it). Note the tracks on lookers right - apparently some people made 'good' use of the crown to get big air ?!
Cheers

Where too go next!! Beautiful British Columbia

It was nice to get the spring sunshine yesterday. Certainly is strong when it breaks out of the clouds. Which quickly became convective clouds.  At 2280 meters as of 06:00 the temperature was - 14, winds were 5-10 KPH from the South. At 1550 meters the temperature was -11, 89 % relative humidity and the barometer is still rising. In the valley it is -8. 1 cm was recorded at pig alley a trace at cat skinner.

Rumours of a 25 year old female falling off a cornice yesterday afternoon in the Piccolo area, she had to go to the clinic for attention. Hope to have more details later today. The cornices are very fragile, use caution and stay well back from them.

There has been 20 cm of settlement in the HS in the past few days.
