Large avalanche on low angle near Livingston

From text: "this one was interesting because it was so low angle and in quite tight trees. We were in a zone south of Livingston today (1/26/19), near 9k’, NE as aspect n dense timber not far from a ridge top. The sl slide ay have been remote triggered by us skinning up or a large wind gust that came from the other side of ridge. We were touring up low angle terrain and had multiple large collapses on our ascent. We came to what was going to be our turn around point where my brother and I were discussing where we would rip skins and drop in. Before we proceeded into the timber on a 28deg slope we noticed a lot of tree bombs then saw the sl slide oming through the trees and taking out a couple of 10” diameter snags along the way. These trees were barely skiable due to how tight they were and the star starting zone only a hair over 30 deg. The crown we could see looked to be 3’, and 300’ wide. I’m unsure on the the distance it ran, but estimate 500-800 vertical ft. The main point I got from this slide was slide we were crowding connected terrain, things are sliding at the very relaxed end of the slope spectrum, and don’t be lulled into a false sense of security in fairly dense timber."
