A huge snow storm rolled in today. Summit has received several feet of snow and the powder is really soft. Walking outside of the camp I've been sinking down to my knees at points. I attempted to take Yeti out this morning and as soon as Yeti passed the berms on the north end of the camp, it sunk past its motor housings. With the continued snow and warm weather coming up, I will be unable to operate Yeti off base for several days.
