Campbell County Rockpile Museum - “Energizing History”

The Campbell County Rockpile Museum focuses on local and regional history with an emphasis on the culture and people of Campbell County, Wyoming and the Powder River Basin. Our mission: "Collect, Preserve, Educate. The Campbell County Rockpile Museum tells the story of the Powder River Basin."


Rockpile Museum exhibits feature collections of fossils, Native American artifacts, rifles, saddles, horse-drawn vehicles, and other ranching, homesteading, and energy industry equipment. Hands-on activities throughout the exhibits make for a fun and informative experience for your group of any size or age. Come watch a video tour of an excavation and blasting at a coal mine and then see how the coal is transported to various locations. The museum has a full schedule of temporary exhibits and educational programming each year. There is something for everyone at the Campbell County Rockpile Museum.

3rd Annual Northeast Wyoming Archaeology Fair CANCELLED, but special guest speaker for Sep. 17th is still a go.

September is Archaeology Awareness Month and unfortunately the Rockpile Museum has had to cancel our annual Archaeology Fair for this year. We look forward to bringing this event back in 2022. That said, please join us at the Rockpile Museum on Friday, September 17th at 6:30 p.m. for a program titled “Messages from Medicine Wheel Country” by Dr. Shane Doyle. The program will cover what we can learn about Native people from the materials and formations they left behind on the Northern Plains. Dr. Shane Doyle, Apsáalooke, will share insight from his research on the ancient cultural geography of the Powder River Country and surrounding region.
