- <p>We went to the area to look at 2 recent avalanches. One was triggered on Monday by 2 snowboarders on Peak 10420. The other was on Clayton Peak and occurred on Sunday.</p>

We looked at the flank from the slide on Lackawaxen. It broke on a thin layer of facets just under an ice crust at 47 cm above the ground, about the middle of the snowpack. What surprised me is how wide and how far downhill this slide fractured. The bottom edge of the slab that released was almost at the toe of the slope. The width of the slide was at least 200ft wide. The slide on Pk 10420 was triggered by two snowboarders mid slope. Both of these features of these two slides are characteristics of faceted layers.
Today, there seemed to be less sensitivity in the snowpack. Based on other snowpits and small test slopes, triggering a slide has gotten harder to do. Spatial variability tends to increase through time until there is some unifying event like a big storm. The odds of triggering a persistent slab avalanche have gone down, unfortunately I don't know exactly how far down they've dropped. This and the spatial variability make for tricky conditions.
Lastly, I dug on a south facing slope at 9200 feet and the snowpack was strong and stable and surprisingly deep.
