Removed from the stomach of a cow that was processed in a nearby packing house, this mammoth trichobezoar was nearly 40 inches in circumference and was said to have weighed 55 pounds wet when first removed. Though smaller and drier now, it’s still a very impressive sight. Visitors are free to lightly touch the ball (it feels like a velvet basketball) but signage politely reminds them not to pick it up. Hairball aside, the museum has several walk-through areas and numerous exhibits where visitors can trace the roots and historical events of the area, from the lives of the first native people, to the cowboy era, all the way up to present day. Volunteers will happily answer any questions you might have as you explore the facility. The grounds also include a research library, an original one-room school house, and a museum store with enough items to satisfy any traveler’s needs, including t-shirts featuring the giant hairball.
