Kirk Johnson coordinated this Snowmass dig. He was a big shot in Colorado, was the VP of the Denver Museum of Natural Science. He's been around, has all the credentials, now he's been appointed to the Smithsonian as the Director of Natural History.
The front range of Colorado has produced some excellent fossil finds, and all around ancient watering holes. Two in the last 50 years on the front range have come from private land owners trying to expand natural springs to make a reservoir. They dug and found bones, those springs were ancient watering holes that still existed.
