Frank W. Osterwald 1967 <p><span>The U.S. Geological Survey, at the request of the rational Park </span><span>Service, participated in a field symposium May </span><span>22-26, </span><span>1967, at Mammoth </span><span>Cave National Park, Kentucky. This symposium, held by the National </span><span>Park Service, was to determine the applicability of the Wilderness </span><span>Act </span><span>of </span><span>1964 to underground and surface portions of the Park (W. Drew </span><span>Chick, Jr., written communication, 1967). Scientific evidence bearing </span><span>on the relationships between human surface activities and natural </span><span>underground openings was examined and discussed at the symposium. </span><span>This report discusses relations between various types of surface </span><span>activities and physical damage to the cave openings and features. </span><span>Additional interpretive material </span><span>is </span><span>taken from the literature and from </span><span>limited laboratory information. Possible hydrologic and biologic </span><span>effects are not considered here, </span><span>but </span><span>were investigated by other </span><span>members of the symposium. Hydrologic effects are discussed in </span><span>companion report by Robert V. Cushman of the Geological Survey. </span></p> application/pdf 10.3133/ofr67173 en U.S. Geological Survey Some engineering geology problems at Mammoth Cave National Park, Kentucky reports
