Milky Way gets a lot of sun exposure. Some friends who were at Sunshine yesterday said the sun was warm. Milky Way tends to be shallow snow compared to other parts of the Dive and is more wind effected. Things go bad quickly with direct sun, especially on those slopes which also tend to be thinner and wind effected. I've seen the slopes in Milky Way and Galaxy slide in past springs (no one was on them at the time) when open, while the rest of the Dive remained good. No one really saw this one coming - Parks changed their avalanche prediction - now warning folks to watch out for sun effected slopes.
This happened a couple of years ago on a run just outside of Taynton at Panorama - great skiing in the AM - slid in the mid afternoon sun and caught a couple of people. Ava patrol checked the nearby slopes in AM and everything was fine. A few hours of heat and sun later, everything was dangerous and all of Taynton was closed.
I agree - the avalanche conditions in this area all year have had an underlying bad layer or two that have made things worrisome. There are several backcountry slopes that I have not gone near because of concern about stability.
