This time lapse, taken over a 17-day road trip across the country, includes locations in Badlands, Grand Teton, Glacier, and Olympic National Parks.
It was featured in the 2016 Philadelphia Flower Show "Explore America," which celebrated the centennial of the National Park Service.
The time lapse ran in the "A Day in the Life of the National Parks" multimedia presentation in the show's central feature, the "Big Timber Lodge," which recreated classic National Park architecture and American horticulture.
