East Slopes South

Very large avalanches have recently released from upper-elevation start zones in adjacent areas.  Travel conservatively by limiting your exposure to large avalanche paths including anywhere they can run, start or stop.  High above you, a cornice failure or a natural wet snow avalanche could step down to a  larger and more destructive slide. 

Very large, deep slab avalanches were reported last Friday through Monday in the southern and central Cascades.  Some of these monsters released naturally several after days after the most recent significant winter storm.  Most recently and closest to the East South zone, a large to very large avalanche naturally released (likely by cornice fall) on Spiral Butte, just east of White Pass Monday.  Very large deep slab avalanches (D3-D3.5) released naturally in the Crystal Mt backcountry last Friday, Saturday and Sunday.  These avalanches would be difficult to survive. 

Treat this ongoing avalanche cycle with respect.  Deep persistent slabs are a low-likelihood, high consequence gamble that has professionals and experienced backcountry travelers alike on edge throughout the region.  Without specific information about the likelihood of triggering a deep persistent slab in the East South Zone, it's just not worth the risk. Limit your exposure to large avalanche paths, sticking to simpler terrain.  

Mild temperatures will continue through Thursday along with mostly sunny skies.  You may trigger loose wet avalanches on steep sunny slopes.  If you find wet surface snow or indicators of increasing instability like rollerballs or pinwheels, move to lower angle terrain or shadier aspects.  Cornices have grown big in some areas.  Avoid going underneath them and give them a wide buffer.  A large cornice failure could wake up the sleeping beast on the slope below. 

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
