locate construction material within the headwaters of the St. John River Basin. A photomosaic was prepared from 1966 black and white photography (scale 1:33,600). Fourteen surficial geology units were delineated in an 1100-square-mile area: alluvial fan, alluvial terrace, esker, floodplain, glacial moraine, kame, kame terrace, outwash, outwash terrace, bedrock, till, till over bedrock, wet outwash and wet till. These units were field checked and the depths estimated utilizing initial boring data, field measurements and seismometer values. Considerable time was saved using remote sensing techniques compared with conventional ground surveys. This comparison showed that the required construction material could be found within the prescribed area around the dam and dike sites. Because transportation of materials is a major cost in dam construction, the reduction in transportation distances determined from this study could result in considerable savings.
