Voas Nature AreaThe Voas Nature Area is a 705 acre park located approximately 1½ miles west of Minburn. The initial 265 acres were donated to the Dallas County Conservation Board by Lyle and Mae Voas. Both brother and sister had a desire to see their family farmland restored to a native prairie and forest condition similar to pre-Euro-American settlement. They intended for the area to become a wildlife refuge and educational center. Additional land has since been acquired, much of it for wetland mitigation initiatives. This has led to the development of two hunting areas, one for youth only, and the other as a general public hunting area.

Vaos Museum Collection 

Lyle and Mae collected rocks, fossils, and minerals from across the United States and around the world. They built a museum to display their impressive collection and other artifacts. Rare native elements, dynamic quartz specimens, and fossils are on exhibit. The museum has been expanded to include an observation deck and modern restrooms.

The Voas Nature Area is diverse in habitat, including 90 acres of oak/hickory forest with most of the remaining acres being a prairie and wetland complex.

The diversity creates as an excellent stage for learning about our natural world. Interpretive programs offered at the Voas Nature Area include tours of the museum, bird-watching hikes, prairie programs, geology presentations, cross-country skiing and many other environmental education programs.
