Avalanche: Seward

Location: Mt. Eeva

Route & General Observations

Skinned up west aspect to ~300ft above treeline and dug a snowpit 1700ft. With warming temps and rapidly rising instability, especially on south facing terrain we stayed to low angle terrain on top of an elevated medial moraine towards the center of the bowl we were in. Skied down from our high point at 2200ft.

Lots of point release R1D1 avalanches and rollerballs actively avalanching as we approached our high point on South Aspects. We avoided potential runout zones by staying on a medial moraine feature well away and elevated above slide paths.
