Geology and ground water resources of Grand Forks County

Grand Forks County in northeastern North Dakota is underlain by glacial drift, westward-dipping Paleozoic and Mesozoic sedimentary rocks and Precambrian igneous and metamorphic rocks. Glacial drift that covers the bedrock reaches a maximum thickness of 455 feet. It can be differentiated into 5 drift sheets, each of which in turn can be separated into till units, lake clay and silt units, and sand and gravel units. Relief on the bedrock surface is much greater than that on the present glacial topography. In western Grand Forks County, the bedrock rises 600 feet from east to west at the Pembina escarpment, whereas the surface elevations rise only 300 feet.

Geology and ground-water resources of the Two Medicine unit and adjacent areas, Blackfeet Indian Reservation, Montana, with a section on chemical quality of water

The Two Medicine Irrigation Unit, on the Blackfeet Indian Reservation of northern Montana, is irrigated by water diverted from Two Medicine Creek. Waterlogging because of overapplication of water and locally inadequate subsurface drainage is a serious problem. This study was undertaken by the U.S. Geological Survey in cooperation with the U.S. Bureau of Indian Affairs to evaluate the problem and to suggest remedies. For this study, the geology was mapped, and data concerning 129 wells and test holes were gathered. The water level in 63 wells was measured periodically. Three test holes were drilled and 4 single-well and 1 multiple-well pump tests were made. Nineteen samples of ground water were collected and analyzed chemically, and applied irrigation water was analyzed periodically.
