This is one of Steven's white whales. He is after the iconic picture of one of these little guys having a load of grass in it's mouth while returning to it hay pile. These little guys live in Talus slopes, typically higher in the mountains.
Moose are the largest member of the deer family. Like all deer, they grow antlers every year that are covered in velvet until about August, when it sheds. The males then will rub against just about anything to remove the velvet and sharpen the points in preparation for mating season.
