From 1907 to 1952, the Lamar Valley was the site of a buffalo-ranching operation designed to revive the park's buffalo population, which had neared extinction. Nowadays, crowds gather there to spot the gray wolves that were reintroduced to the park in 1995. The best time to see wolves is early morning in the spring, early summer or winter. Also watch for bison, elk and moose—as well as the occasional grizzly or black bear. The road through the Lamar Valley is plowed year-round. Between Tower/Roosevelt and the Northeast Entrance, Yellowstone National Park.
