Abstract or Summary
  • An investigation was conducted to determine the origin of Mima mounds in Jackson County, Oregon and Thurston County, Washington. Data on soil morphology, mineralogy, and particle size distribution were used to test the periglacial ice wedge hypothesis, the gopher hypothesis, the erosional hypothesis, and the loess hypothesis. The results of this investigation show that these hypotheses do not satisfactorily explain the origin of Mima mounds. The conditions of an acceptable hypothesis are given and a depositional theory on the origin of Mima mounds is suggested within the framework of these conditions.
