Comments
Toured up White Pine to see how the summer snowpack is setting up. The best way I can describe today is 'soupy.' Even before the sun came out, the new snow was wet and rapidly consolidating (in the 3hrs I was out, it had consolidated about 3"). There were no signs of instability until I got to a meadow below Rainbow Peak/Dog Dish. While I was out in the middle of the meadow, I got a massive collapse. After that, every couple steps I took I would get a giant collapse. By the end of the day, I probably had about 20 of these large collapses. I dug a quick pit and my best hypothesis (I am not an avalanche expert) is that the weak layer of refrozen grains below the ice layer of the old snow is what is collapsing. I think the likelihood of this layer failing and propagating is low.
Based on what I saw today, the danger seems to be a solid moderate and will stay that way until we get a couple freeze-thaw cycles in.
