Southside Conditions: Old Ski Bowl, Grey Butte tour
The northwesterly winds kicked in again this morning with an impressive lenticular cloud stationed on the upper mountain. Strong winds were observed in the Old Ski Bowl as we practiced avalanche rescue between 9 a.m. and 11 a.m. Skies cleared by noon, and the winds died down as well. Without the breeze, it was possible to feel the extent of the temperature rise.

After the snowmobile avalanche awareness course, we took a tour of Old Ski Bowl and around Gray Butte to look at conditions. The winds had died down at this point, and it wasn't long before we were taking off layers and wiping sweat from our brows. We noticed rollerballs forming on southerly aspects, and trees began to drip by mid-afternoon. Looking at the upper mountain, it's hard to miss the scoured north and westerly aspect of ridges and moraine tops. However, snow surfaces below and near treeline remain smooth. The woods are ridable, but I wouldn't throw caution to the wind. Many rocks, logs, and bushes remain barely hidden. There were no obvious signs of avalanche danger or instabilities observed today.
