A slab 12-20” thick is sitting on a fragile layer of buried surface hoar. This persistent weak layer is widespread and has been found on all aspect above treeline throughout Turnagain Pass and Summit Lake. Over fifteen human triggered avalanches were reported throughout the weekend and three more occurred yesterday on Tincan. Luckily no one has been buried or injured. Click HERE for more details on these observations.
Note worthy things to keep in mind today:
Although many of these avalanches have been relatively small, don’t forget that BIGGER SLOPES WILL HAVE BIGGER CONSIQUENCES! As we move away from the weather events that caused this scary set-up, remember this type of avalanche problem will be slow to heal. The next few days of clear weather are going to be tough to resist the temptation to get into bigger terrain. Avoid high consequence terrain and keep your slope angles low. Cautious route-finding and conservative decision-making will be necessary!
This small avalanche was triggered remotely by two skiers putting in a skin track at 2200′ on a North aspect on Tincan yesterday.

Yesterday skies were partly cloudy following a storm that left 5 € of new snow in Turnagain Pass and brought moderate Easterly winds with gust into the 40’s mph. By mid afternoon ridgetop winds began to decrease into the teens mph. Rain/snow line briefly reached 1200′ yesterday morning, but temperatures cooled as skies cleared late morning. In the upper elevations temperatures averaged in the mid 20Fs.
Overnight winds were light from the East. Temperatures were in the mid to low 20’s F with a slight inversion causing ridgetop temperatures to be warmer than at road level. No precipitation was recorded.
Today skies are expected to be mostly clear with light winds from the East. Daytime temperatures will be in the high 20s F and no precipitation is expected today. This pattern is expected to last through Thanksgiving day with our next chance for snow showers near the end of the week.
