Officially announced in January of 2017 as part of Governor Brian Sandovals Explore Your Nevada Initiative, this 315 acre park features a portion of the upper Las Vegas wash that is rich in both paleontological and historical resources. During the Pleistocene, also known as the Ice Age, the wash provided verdant habitat for several species of now extinct mammals, including Columbian mammoths, American lions, camels, dire wolves, and ground sloths. The discovery of abundant fossils onsite triggered a long history of scientific research, which includes the famous Big Dig of 1962-3, the largest inter-disciplinary scientific expedition of its kind up to that point.

Although there is currently no existing infrastructure onsite, the park will feature a modern visitor center and a network of interpretive trails that will take visitors out to the fossil beds and Big Dig localities. The grand opening of the park is planned for summer 2020.
