Where are we going today?

Some of the world's best preserved fossils are found in the flat-topped ridges of southwestern Wyoming's cold sagebrush desert. Fossilized fish, insects, plants, reptiles, birds, and mammals are exceptional for their abundance, variety, and detail of preservation. Most remarkable is the story they tell of ancient life in a sub-tropical landscape.

    Very cool little place, nice little educational building with many really interesting examples of fossils. I hope to get back here again someday.

    It's an okay stop. Really lacking in material though, and information. It is free to enter so it's not too bad.
