Abstract
A recent mine-subsidence related mishap in the What Cheer, Iowa vicinity is dramatic evidence for concern over the continuing problem of mine subsidence in Iowa. A large portion of the What Cheer community is undermined, however most mines cannot be accurately located. Sixty of the one hundred identified mines in the area are plotted or mapped. Subsidence, or collapse of surface materials into old mines in the What Cheer area, is primarily expressed as sinkholes or craters. Several subsidence events are documented, some with photos. A complete listing of the State Mine Inspectors' Reports is provided.
