Comments
<p>This was the second of two avalanches and was a much more dangerous avalanche than the first.&nbsp; This was at least 4 feet deep and produced a large pile of debris some of which was pushed into a gully where it piled up quite deep.&nbsp;</p> <p>The Fish Lake Region has some quite weak snow from the ground up to around 18&quot; above the ground.&nbsp; The recent storm added enough weight in wind loaded areas to create a danger to motorized users who might venture into this terrain.&nbsp; In most areas, this weakness is not reactive right now.&nbsp; It appears that you need to be in an area that has additional snow from the winds, in other words, you need a slope that has been drifted in pretty deep on top of this weakness.&nbsp; The weakness is most pronounced on west through north through east facing slopes.&nbsp; The new wind loads are primarily on the more easterly facing slopes.&nbsp; The slopes need to be over 35 degrees in steepness.</p>
