DATE OF OBSERVATION: 02/07/2015
NAME: Irwin guides level 1
ASPECT: North, North East, South, West
ELEVATION: 9000-10500
AVALANCHES: None observed.
WEATHER: Increasing clouds in the pm, light variable winds, intense solar
SNOWPACK: Wet snow surfaces on west and even northerly terrain in trees. Numerous profiles on north to northeast facing slopes revealed two persistent slabs, one 20-40cm deep resting on 10-16mm preserved surface hoar, widespread in areas we dug. The older December 13th slab definitely has lost cohesiveness and no results were observed with compression tests or ECT.
Note able results: 2 x ECTP (17 and 23 taps respectively). SC on the surface hoar on 42 degree wind loaded rollover feature, northeast facing. Other tests preformed found surface but did not produce propagating results.
12mm Surface observed 2.8.15 buried 40cm deep.
