In the vicinity of Cedar Rapids there are extensive deposits of laminated sands within, and adjacent to the valley of the Cedar River and its tributaries. These lie above the till of the Iowan Substage and are associated for the most part with the highest terrace found along the Cedar River and its tributaries in Linn County. The presence of the laminated sediments has been noted by others, but no detailed study appears to have been made of them in the region of Cedar Rapids. During the active building program in Cedar Rapids many exposures were made in basement excavations and furnished a good opportunity for study.
