Where Great Plains merge into Black Hills, Wind Cave National Park is a little-appreciated treasure well south of all the tourist attractions, but loaded with natural beauty above ground as well as beneath. That included the sky on this pleasant evening; a gorgeous cumulonimbus with rainshafts, hailshafts, and a splash of mammatus raced past, while both storm and landscape bathed in the lovely light of the golden hour.
