A grouping of moose spend some down time and enjoy the view of the Grand Teton Mountain Range. Moose are found in the boreal and northern woodlands of North America. Moose are the largest member of the deer family. Bull moose can weigh up to 1,500 pounds and can run up to 35 mph. During the mating season, moose have even been known to challenge oncoming vehicles and trains in defense of their females and their territories.
