On 2/16/24 GNFAC forecasters rode up Denny Creek below Lionhead Ridge, then around to the north, through Watkins Creek and into the top of Targhee Creek. We saw a lot of old and recent avalanches that happened at various times over the last week, including during an avalanche warning on 2/15, in a wide variety of terrain. On lower elevation, generally non-wind-loaded terrain in the trees we saw at least 4 avalanches that were at least 2' deep and 100' wide. Near ridgelines there were many avalanches, harder slabs, at least 2' deep breaking hundreds of feet wide.
