Worth enlarging. Taken at Theodore Roosevelt National Park in North Dakota - those cannonballs concretions were absolutely fascinating. I always thought a rock was a rock was a rock! Nope.
Wow! Those formations must be the benchmark for 'weird and wonderful', they're fabulous and so intriguing. It's great to get the opportunity to see something so astounding that I would never have seen otherwise, so thank you.
