Yellowstone National Park administrators are reporting that more than 3 million people visited the park over the summer.
That marks the third straight year the park has broken the 3 million visitor mark during the park's peak season from May through September. That was down just over 6 percent from last year's record 3.3 million summer visitors.
Park officials said the high numbers came despite snow and ice that lingered into May and several road closures caused by rockslides and avalanches.
By comparison, the park recorded fewer than a quarter-million visitors last year from October through December.
The nation's first national park, Yellowstone includes portions of Wyoming, Montana and Idaho.
