Grand Valley (Madill Field)

The specific reason for closure is not officially documented. However, as a private airfield owned and operated by an individual (John Madill), the closure was almost certainly due to personal circumstances. Common reasons for such closures include the owner's retirement, death, the sale of the land for more profitable use (like agriculture), or the rising costs and liability of operating a private airfield.

The site is currently private property and is used for agriculture. High-resolution satellite imagery of the coordinates shows that the land has been converted into farmland. While the distinct outlines of the former grass runways are still faintly visible within the cultivated fields, all aviation infrastructure has been removed or repurposed. The land is not used for any aviation activities.

Grand Valley (Madill Field) was a notable private general aviation airfield that served the local flying community for several decades, from at least the 1970s through the early 2000s. It consisted of two grass runways, approximately 2,400 ft and 1,800 ft long, in an 'L' configuration. The field was primarily used for recreational flying by pilots of small, single-engine aircraft. Its significance was as a classic example of a private 'grass strip' aerodrome, providing a base for local pilots and serving as a visual landmark for aviators navigating the region.

There are no known plans or prospects for reopening Grand Valley (Madill Field). The airfield has been permanently closed for nearly two decades, and the land has been fully integrated into agricultural operations. Re-establishing an airport on the site would require significant investment and regulatory approval, making it extremely unlikely.
