Theodore Roosevelt National Park, North Dakota
We were walking along the Ridgeline Nature Trail in the south unit of the park at about 10:00 a.m. Our friends were walking in front of me and startled the snake. It crawled up a steep dirt slope and disappeared into brush. I had time to take three photos.
It was about 15 inches long.
Here’s a blow-up of the second photo in which you can see the distinctive nose.
