Observation: Turnagain
Location: Tincan
Toured up the standard West ridge and traversed to the Northwest ridge above CFR. Test pits above CFR showed moderate reactivity on the valentines day (near surface facets) 5-8″ below the surface and one test had propagation on this layer Ascended the NW ridge to Todd’s bowl. Dug a pit at 3500′ in the starting zone of Todd’s. Found good stability and no results in Compression tests.
Observer Comments
Weather
Clear and sunny
Temps teens F to mid 20s F - warming with elevation
Light North wind shifted to the South by late afternoon
No precip
Snow surface
1000-1500': Patches of surface hoar (4-8mm) on 6-7" loose snow (near surface facets)
1500' - 2000': 6-7" loose snow (near surface facets)
2000' - 3500': wind scoured ridges, 4-5" of settle snow (near surface facets) in many places, and 1-2cm sun crust on steep due South aspects.
Snowpack
Dug two pits along the NW ridge above CFR, one pit on a West aspect and the other on North. The only reactive layer in tests was the valentines days near surface facets found at ~2650' under a slab that was 5-7" thick.
Pit 1 - 2628' - W Aspect - 22 degree - HS:275cm
STM, CT3, ECTN18 down 15cm on vday facets (.5mm PP/Frags)
SSH down 75cm MLK BSH sitting on top of faceting grains.
Pit 2- 2645' - N Aspect - 30 degrees - HS:220cm
CT11. ECTP13, ECTN14 down 20cm on vday facets (1mm)
MLK layer not found within top 115cm
Pit 3 - 3556' - N Aspect (Todd's)- 28 degrees - HS:155cm
MLK layer 20cm down 5mm non reactive (very thin MF crust (2mm) above and below 6-10mm buried surface hoar)
STM down 30cm in 1mm facets (not MLK or vday)
1-1.5mm facet/MF layer down 60cm non reactive
CTN x 2
1cm sun crust on a 35 degree due South aspect at 2500' - was just starting to become moist at 1pm
Common Bowl
Glide crack and some tracks on SW aspect of Eddies. Within several of these gullies wet loose could be seen below rocks
Kick step
MLK buried surface hoar was found 20cm below the surface at 3500' in Todd's bowl, but was unreactive.
Glide crack slowing opening along SE face of Seattle Ridge Repeat Offender near the up-track
Large wet loose avalanches seen near Portage. These likely released naturally on Monday when air temps reached upper 30s F.
Even the wind scoured ridges were fairly soft and faceting out, especially on shaded aspects
