"Along the Lower Geyser Basin we waved at sightseers standing beside the tanklike snowmobiles that had brought them over the snowbound road from West Yellowstone. The day is perhaps not far off when large number of visitors, bundled up in snowmobiles, will see much more of the park's winter beauty. When that day comes, fleets of steel-treaded half-tracks will rumble across a land that once knew only the snowshoes of Indians and trappers."For more on the parks, and to see other classic photo galleries, visit our National Parks guide.
