My winter visit to Yellowstone National Park was organized and led by Barbara Eddy and John Gurlach. In the wintertime, one cannot simply drive into the park. The Gerlach team led us on wonderful excursions for five days, rising before sunrise and shooting until it was too dark.
Theodore Roosevelt National Park in North Dakota requires the visitor to search for beauty within the 36 mile vehicle loop, unlike some of the more spectacular national parks such as Bryce Canyon, Grand Canyon or Zion. On any random visit, a lucky visitor might possibly be blessed with stormy rain clouds, clearing storms or special light. More typically, on a hot clear blue sky day, you must really search for the attractiveness of the park.
