This diorama is one of the best I’ve seen, and it showcases all the major finds discovered here to date. The first fossil was found by James Cook on his ranch here at the headwaters of the Niobrara, but his collection of Native American art & artifacts rivals the attraction of the fossils. He was a great friend of Chief Red Cloud, and, unlike many of the original fossils which have gone on for display and study elsewhere, Cook insisted his gifts remain here. If that weren’t enough, there’s a lovely creek with wildlife on the trail up to where most of the fossils were found. This is one of my favorite fossil sites, although Dinosaur is better.
