Reactive storm slab

rfehr65, Saturday 23rd December, 2023 8:10AM

Glacier

Excellent conditions in the alpine yesterday. No signs of recent instability observed,. A size 2.5-3 avalanche ran from mid slope to valley bottom, likely prior to or during the last storm cycle.

Great corn skiing in the Nass

<p>Great corn skiing down Sand yesterday. It was colder than expected on the summit ridge and the snowpack was in great shape. There was some extensive whumpfing on the flat spots along the way up, but otherwise nothing else to report. Not much activity around neither apart from a few small wet loose on Oscar.</p>

Windy and a little warm

<p>Skied Wolf's Den today. It was snowing to the highway but this storm definitely came in both warmer and windier than the last few. Roughly 15cms of new snow by midday but it was hard to say for sure because of wind transport. Widespread windslabs were forming throughout the morning in open areas on the west-facing terrain at Wolf's Den. Ski quality was good but continued wind might make it worse.</p>

Sterling Glide Crack

<p>Observed large (100m+) glide crack to base of snow pack on south facing slope at 1400m elevation. No other avalanche activity observed.</p>

Zerippin and Alberta Clippin

<p>Today we skied north of Terrace at Inbetweeners, travelling on west and southwest slopes at treeline and below. We had poor visibility, strong southwesterly winds in open areas and at ridgecrest, and continued snow throughout the day. We didn’t see any new avalanches but we didn’t see much! We avoided lee slopes (north and east facing slopes) where we suspect wind slabs have formed. On west facing slopes, near the top of treeline, we found 20 to 35 cm of soft slab over a stiffer older wind affected surface. It was easy to break off hand shears up to 35 cm deep at this interface, however we experienced no cracking or whumpfing. We found the late January rain crust 105 cm deep. We had good skiing in the trees in sheltered areas where winds had not effected the surface snow. We found 10 cm of new snow below treeline over a thin, breakable crust. This crust exists up to about 1000 m. </p>

The Mark of Zeerip

<p>Today we sled-skied near Terrace and experienced strong southwesterly winds and continued light snow throughout the day. We didn’t see any new avalanches but as we neared ridgecrest and open areas in the treeline we were able to get shooting cracks 15 cm deep. We dug at 1200 m on a west facing slope and found 350 cm total snow depth. We were able to produce compression test results 40 cm with moderate loading steps that progressively compressed underneath the shovel blade. The January 28 rain crust is 165 cm deep showing just how much storm snow we have had in the last few weeks! There are some small facets above the rain crust but we did not get any results on this layer. There is another rain crust from during the storm cycle last week that exists up to 950 m. It is breakable makes travel and skiing/riding below this elevation quite challenging.</p>

Two Blind Mice, see how they ski

<p>Today we went sled skiing in the Sterling Creek drainage, north of Terrace. We had poor visibility with a trace of light snow throughout the day. We saw no new avalanches but we didn't really see much at all. We found up to 10 cm of new snow in sheltered areas, but the north aspects had up to 30 cm from recent wind loading. We dug at tree line on an east aspect at 1300 m where we found two weak layers that are identified in the avalanche bulletin. There was a layer of surface hoar (Jan 9) down 30 cm that failed easily on compression tests (CTE 5 SC down 30 cm on 5mm SH). Also the Dec 23 layer failed on hard taps (CTH 26 RP down 65 cm on 2 mm FC). The freezing level was around 1000 m with good skiing above. </p>

wolf den

<p>highly variable snow, wet and heavy in the trees, treeline observed some debris , and alpine wind effected. No observed signs of instability, or recent slides. Ski tracks still left from several days before. Still fun walk up and a few nice turns, logging road fully covered to the hwy. </p>

Wolfs Den

<p>In the cloud all day. 15-20cm new, little to no snow most of morning/afternoon, S-1 in early afternoon. Light wind from west. Some wind effect in upper few cm. Excellent ski quality in general.</p>
