Avalanche Summary
Several small (size 1) natural and human triggered avalanches were reported during the stormy weather over the weekend and into Monday. These included both slab and loose avalanches in the top 15-30 cm of new snow, primarily on north and east facing slopes.
Snowpack Summary
Recent flurries delivered 15 to 30 cm of snow, which has been wind affected in open terrain and is quickly settling due to mild temperatures. This snow covers a wide variety of hard layers, including wind-affected snow on alpine slopes and a sun crust on steep south-facing slopes. A widespread crust layer from mid-February is 50 to 100 cm deep in the western side of the range and 25 to 50 cm deep on the eastern side. The snowpack is generally well settled below this crust.
Terrain and Travel
- Be carefull around freshly wind loaded features.
- Use ridges or ribs to avoid areas of wind loaded snow.
- Use caution when approaching steep and rocky terrian.
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
