** What It's Like**
When the annual autumn migration to their winter range begins in late August, small local bands of caribou join up with others and begin to drift south and east. To find them, you'll spend each day hiking high land, glassing for caribou on the move. Despite the openness of the country, caribou blend in and are surprisingly difficult to spot. Distances are hard to judge on the open tundra because there is nothing of known size to compare things to. Although you are looking for animals larger than whitetail deer, what you see may appear as a tiny line of ants, depending on the distance. Often, smaller migratory bands of caribou will act as magnets wherever they pass, attracting ever increasing numbers until the growing herds become huge masses of animals that get jammed together at water crossings, or strung out in lines that pass for hours.
