Highlights

The majority of the terrain on the Manti Skyline has a LOW avalanche danger.

However, a CONSIDERABLE danger still exists on slopes steeper than 30 degrees that face northwest, north and northeast above about 10,000'.

Large and dangerous human triggered avalanches are still likely in that terrain.

    Second verse, same as the first!! Steep high elevation northerly facing slopes remain suspect. The mid winter Persistent Weak Layer just will not go away. Unprecedented. We will look back at this situation for years to come. The most likely place to trigger an avalanche is in the terrain described below:

    • Above 10,000'
    • Northwest, north and northeast facing slopes
    • Slopes steeper than 30 degrees. (to be honest, slopes need to be steeper than 35 degrees to avalanche right now but 30 degrees is the number you should use to stay safe)

    If you avoid that terrain, you will not trigger one of these large avalanches. Avoidance is the only sure mitigation tool.

Recent Activity

I went and looked at an avalanche on the Towhead yesterday. There were actually two of them side by side. They most likely released naturally on Thursday due to wind loading. This fits in with the current pattern: high elevation, northerly facing, very steep starting zone, broke into mid winter Persistent Weak Layer. However, this is the only natural activity that I've heard of recently.

Snow and Weather

Current Conditions

Sunday ended up being a nicer day than anticipated with the cloud cover more translucent and enough sun filtering through to actually make shadows. Riding was good again. The snow surface should have frozen up again decently overnight with low temperatures in the upper 20s to around freezing. The wind has been almost calm.

Mountain Weather

Today will start out really nice and then clouds will move in later on. Temperatures will get into the mid 40s. West southwest wind will increase as the day goes on and might be pretty strong later. We have a storm moving through tonight but it's looking less impressive than it did. I'm thinking we'll see only a few inches of snow by Tuesday morning. The rest of the week looks sunny with gradually warming temperatures.
