Avalanche Summary
Nothing new has been noted in the last couple of days but still lots of older signs of avalanche activity.
Snowpack Summary
We have about 20cm of snow in the valley bottom and 40-70cm at treeline and above. Variability in snow amounts is the theme here but generally not enough to ski yet. Lee features and cross loaded gullies will have the most snow but are also areas of concern for triggering slab avalanches. As a very general summary, we have 3 layers: sugary facets on the ground, a thin intermittent crust and a persistent slab in wind prone areas. If you're at all experienced in the Rockies, you'll simply know this as a classic early season snowpack!
Weather Summary
Cooler temperatures are moving back into the region overnight on Wednesday with light northwesterly winds and some light flurries. Wednesday night and into thursday we will see up to 10cm of snow as winds continue to shift around to the northeast.

Terrain and Travel Advice
- Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
- Avoid lee and cross-loaded terrain.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Avoid terrain traps where the consequence of any avalanche could be serious.
Avalanche Problems
Persistent Slabs
Slabs are reactive on the basal facets and possibly an intact crust at lower elevations.
