We were on the southside of Skookum Drainage on a north aspect and a glide
crack broke to the dirt. It was about 150 or so yards wide and about 200 yards
long down to dirt. There was huge snow chunks in the debris path after it
settled. Some snowmachiners on the opposite side of the drainage heard it and
then saw the dust cloud. No one was caught in it, we had just cleared the
debris path by about 30 seconds or so.
