Snowpack

Dug a quick test pit to get an idea of stuff to come and how things are shaping in the backyard. N/ne aspect 2185m 35 degrees. Standerd compression test was CTN both times. One tampered with test due to a rock failed Sudden on ctm 11 on the decomposing crust 70cm down(results null and void as it wasn't repeated). Snow pack synopsis for that area. (Taylor lake). Pit area was sheltered free of sun and likely free of wind effect tree line terrain. Top 30cm was settled storm snow that has started faceting. Fist density. And dry. Bottem 70cm was facets growing larger in size till the ground but remained 4finger density all the way through. Straighted facets near the ground but not depth hoar yet. Two crusts, 100cm down and 70cm down. Both decomposing. After seeing the crust move with a likely trigger point I desired to recreate a deep tap test in an ideal location with out the rock. Received dct11 down 70cm on crusts, sudden result. Drawing the conclusion that with the right trigger point or shallow area this layer is still reactive to larger loads or location specific instabilty. Didn't do a saw prop or ect test to test propensity and energy but I assume what's there won't go big without the right load and terrain or diff snow laying atop what was found(wind slabs or denser slabs). Skied pillows steep chutes all low consequence tree line terrain. Unsupported stuff as well, twice we pulled out a 40cm deep under ski length block on the side walls of the chutes showing the propagation was small but so was the features. New snow sliding on old facets largely just turned into big sluffs after the fact. If I could give abit of travel advice id say the skiing is excellent or better in sheltered treeline zones where the winds haven't touched it. No signs.of instability or recent avalanches well on our walk about. The alpine seems to have lots of billowing pillow like texture from afar and also seems to still be holding alot on steep un skiable terrain, the next wind event may push things around alot and also knock alot of this down( ice climber and couloir skier specific talk). I guess it's worth it to note that everything seems to be bonded but the cold temps are giving us our classic weak snowpack mash up and destroying most cohesive bonds that currently exist. Play safe. ( this report is specific to this area and likely will be diff in many other locations of the lake Louise region as the weather in alot of these zones has varied in such a close space) thanks forecasters for doing ur best :)
