 During the Alaska gold rush, one way to reach the Klondike was over the Chilkoot Pass. A stationary camera is placed to see a ways down the curving trail. A pack train comes into view and passes in front of us, led by a man on horseback. Eight loaded mules follow, then another cowboy on horseback and a man walking, then eight more laden mules, another cowboy, then nine more mules, a cowboy, and still the pack train stretches as far as the eye can see. A solitary man watches from atop a hillock.
