Theodore Roosevelt National Park

Russ and I spent three full days in North Dakota over Memorial Day Weekend. I’d passed through the park on my way West several times in the past and decided it was worth more time. I’m so glad we did it. Even though not many touristy things were open yet, we kept busy exploring the natural wonders of the park and area surrounding the town of Medora.

For my next few posts, I’ll be sharing photo stories as inspiration strikes. This first is about “concretions.” These were a highlight of our visit to the North Unit of the park.

These cannonball-shaped formations are made of sand grains from an ancient river that were cemented together by minerals dissolved in groundwater. That’s the official word. Unofficially, I’d say they remind me of Godzilla eggs.

Concretions and sky.
