blue calm day, there has been very little wind damage which is surprising for the Plateau, temps are climbing, March Sun high in the sky, make you feel like ants under magnifying glass.

2.5-"2.9" of water total for last storm, our second major avalanche cycle of the plateau, much like earlier cycle. Most slides that occurred were repeaters, shallow pack from previous slides combined with weeks and weeks of no weather made for tender spots, having a good idea of what had run becomes very important. Where the pack is thicker, warm temps are stabilizing things and now 3 days after storm, we only had a couple of collapses near trees in heavier timbered areas, but not a peep from the Big Meadow. Coverage is vastly improved but new snow has not yet completely settled into the go anywhere conditions that existed before the storm. Machines still struggling to get into more extreme terrain, but Steve reports last Wednesday was the busiest day in the are for snow machines he could remember (at least in recent history). They were also showing up today enmasse as we were leaving, and being somewhat limited in initial terrain, had track out areas we were not used to seeing them in like around the popular shuttle points for snowboarders near the Wasatch Academy area. Skiing on the other hand was excellent with 6"-8" penetration on a spongy base. No new activity noted today, but highly suspect of rocky shallow sheltered extreme terrain that landmines are still likely hiding in.

South facing slopes have the usual heating issues and potential for wet slides, but a lot of areas had nearly burned off in the February drought

no doubt you can still get into trouble on N facing steep rocky terrain, particularly paths that ran during the only other avalanche cycle on the Plateau this year.

nuff said above, this could persist in certain areas, pockety, and hard to determine without good history

while not huge by the usual standards, heating is making them droopy and adding more stress

closer look at repeater pocket in Big Meadow

we felt OK with the entire slope but did limit our skiing today to 30 degrees and less
