Avalanche Details

A very interesting wet slab cycle has been occurring around Turnagain Pass. Most of these slabs are on northerly (ish) shaded aspects; the last aspects to feel the heat of spring. Most of these are releasing in the 2000-3000' elevation band and are quite deep (3-8' or so). We are suspect that they are sliding on the Halloween crust formed in the beginning of the season.
