Avalanche Activity
There was a widespread avalanche cycle on Nov. 26th, as the last storm warmed up bringing rain-on-snow up to 4500ft. D2-D3 Wet slabs occurred on all aspects above 3500ft. Crown depths were around 30cm, with the failure layer being weak/facetted snow sitting on our previous rain crust.
Weather
We had a very wet October and November, with snow levels about 1,000ft above average, near 3500ft. Above that level there was good accumulation, with almost nothing below it. December has started off with some drier and cooler weather although that should change beginning today.

Additional Information
If you get out riding, please send in an observation!
Start the season with fresh batteries in your beacon, and do a rescue practice with your partners. Always carry a beacon, shovel, and probe, and KNOW HOW TO USE THEM.
Practice good risk management, which means only expose one person at a time to slopes 30 degrees and steeper, make group communication and unanimous decision making a priority, and choose your terrain wisely: eliminating unnecessary exposure and planning out your safe zones and escape routes.
