We spent two days touring Theodore Roosevelt National Park in North Dakoda recently. We were pleasantly surprised to find out the beauty of the landscape of the Park, especially the North Unit and with our luck the fall foliage of cottonwood and aspen trees really added the bright colors to the landscape. The rock formation with different colors each layer was just magnificent. The bison we came across on the road certainly added the extra excitement for photo taking.

I’d never heard of this park! Gosh I’m going to immediately add it to my list of places to visit. Beautiful photos.
Thank you! It was a more beautiful place than I expected! Timing was right, mid Sept. for cottonwood and aspen trees to change color to bright yellow. And like any photography early morning and late afternoon are the best time to see the color of rock formation!
