Once verdant pasture, this land is now a picture of blow sand and prickley pear cactus. It offers a vivid example of how land can virtually be destroyed when it is misused-in this case severly overgrazed. Covering 200 acres, the area is now open to the public to visit any time and offers an excellent place for cross country skiing. Nature lovers can see pine, cottonwood, and cyprus trees, native grasses and flowers, prickley pear cactus andmany others. 3 miles south of Mineral on County Road AA is the Witness Tree. A giant bur oak, that gets its name because it was the witness (or reference point) for surveyors, when the Chicago, Rock Island and Pacific Railroad was being built through Mineral Township.
