From the museum web site:
Organized by the University of Wyoming, this display of photographs highlights the abundance of pronghorn (commonly--but mistakenly--known as "antelope") in Wyoming. At the time the exhibit was organized, there were more pronghorn living in the state than human residents. View the many ways that people and the pronghorn have interacted over the years, and learn about the important role these animals maintain in our state as well as around the world.
