From Purpose and Scope of Report: This report presents a detailed description of the ore deposits of the Picher field and all phases of geology having a bearing on their localization, origin, and the search for them. It is based mainly on work done by the U.S. Geological Survey, but it also incorporates pertinent data from published literature, especially from the outstanding work of George M. Fowler and associates, and some unpublished data obtained from the geologic staffs of the mining companies.

Report describing a study to use remote-sensing techniques to look for relationships between disturbances of the land, water, and vegetation with underground coal mines in the Cherry Creek basin of Kansas. The study looked at color and color-infared photographs, compared with water-quality data to successfully identify contamination and other potential problems.
