Route & General Observations

Quick trip up to Seattle Ridge to check on the new snow. Only got to the top of the up-track due to low visibility issues…

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Overcast to obscured skies. Light snowfall with gusty East winds on the Ridgetop. Temperature around 32F at parking lot that cooled with increasing elevation.

Snow surface

At treeline there was around 16" of new snow from Saturday - it is hard to tell how much of this fell last night - maybe 6"?
Snow is wet at 1,000' but becomes much nicer and drier above 2,000'.

Snowpack

We dug a quick pit at 2,300', SE facing, to see how the new snow was bonding/reacting. We found ~16" of 'right-side-up' storm snow (fist hard over 1 finger hardness). This area was slightly wind loaded (intentional) with a total depth of 3m. The new snow was bonding well with the old surface and we could not find any weaknesses in either the new snow or the old/new interface. We did look for buried surface hoar at the interface but did not find any.

It seemed to me that the new snow is sticking and bonding quickly. I would however, not have jumped into a recently windloaded steep slope today. Winds were moving snow around at the upper elevations and I'm guessing touchy fresh wind slabs were present.

We also took a look at the bottom on the gullies along Seattle ridge for any new dirty glide avalanche debris (vis was too poor to see upper slopes well). We did not see anything new - the old debris piles are becoming less visible as they get snowed over.
