Seven-Years Ago (25-August-2009) — North Dakota

Gone to See North America Road Trip. Day 04: Theodore Roosevelt National Park, North Dakota.

Sunrise over the fog covered Missouri River at an overlook in Theodore Roosevelt National Park. Image taken with a Nikon D300 camera and 18-200 mm VR lens (ISO 200, 60 mm, f/22, 1/100 sec).

I didn’t sleep well thinking about the Bison wandering around the campsite. I got up early to a thick fog. I drove slowly up to a higher overlook for sunrise, and was rewarded to an amazing sunrise. When I turned around there was an even better picture –for another post.
