Route & General Observations

We toured up Center Ridge to learn about snowpack during our level 1 avalanche class. We found good structure, good strength, and no propagation potential in our pits. The 5-10mm surface hoar that existed the previous day at 1,200′ was covered with 1″ of new snow. We found very good stability on a beautiful day.

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

It was a very cold and beautiful day. Mostly sunny, calm, and -4 F in the parking lot.

Snow surface

There was 1" of new snow on top of 5-10mm surface hoar. Below that is 1' of faceting snow on top of a thick crust.

Snowpack

We dug several pits all at about 1,200' on west, southwest, and southeast aspects. We found good structure, good strength and no propagation potential. We had one result out of all the tests performed. ECTN18, 1' (30cm) down on the interface between the fist and one finger hardness layers (see photo). We were able to trigger some loose snow avalanches on some steep test slopes. If there had been any steep slopes close by there would have been very good skiing at this elevation!
