|Location:||Upper Seattle Creek drainage, headwall area|
Route & General Observations
Rode into the upper portions of Seattle Creek drainage to look at the problem weak layer plaguing the region currently.
Mostly sunny, temps in the upper 20's F and light easterly winds.
4-8" of low density powder snow.
Small surface hoar growing on top (2-5mm)
We dug several snowpits to see what the MLK BSH layer (Martin Luther King Jr. Buried Surface Hoar) was doing.
NE, 3,300', 20 degree slope
CT 24, 40cm down on MLK BSH
ECTN 30+, same layer
N, 3,100', 30 degree slope
ECTX, could not find the MLK BSH
E, 3,000, 15 degree slope
2x ECTN, 35cm down in the MLK BSH mixed with facets
Pit #4 Repeat Offender slide path:
E 2,500', 15 degree slope
ECTP 19, 40cm down MLK BSH
2x EXTN 30+, same layer
Bottom line: We found the worrisome layer roughly 14-20" down in all pits but one on a N aspect. Only one pit (2,500' Repeat Offender slide path) showed propagation potential. Although these stability tests are showing a strengthening snowpack, these tests cannot be trusted unfortunately. As seen in the events on Eddies ridge from yesterday (Feb, 6).
