The caribou are the only deer family to carry antlers both on males and females. They also travel in herds and migrate great distances to graze on alpine vegetation. Moose are the deer family's largest members and do not migrate in herds. Most people understand the danger of being near a grizzly with her cubs, but moose can be just as dangerous and protective of their calves. The calves stay with their mothers for up to two years and should be avoided throughout this period.
Marmots are large rodents found on the rocky slopes of Alaskan mountains.
They are gray and have dark heads, feet, and tails. They have a unique communication system that consists of 40 different whistles, each meaning something different. Dall sheep are common in alpine areas, but we were unable to view them at Denali. However, we did get to see them on a mountainside south of Denali near Turnagain Arm. Dall sheep have horns on both sexes, but the males' horns are bigger.
