About one-half mile above the confluence of the Iowa and Cedar Rivers, the Iowa makes a great bend from a southwesterly to a southeasterly direction. The river on the outerside of this curve is rapidly cutting at the base of a high bluff for a distance of about one-third of a mile. The bluff extends beyond at each end, bounding the flood plain, but at some distance from the stream. The bluff is composed chiefly of Kansan drift overlain by Iowan loess, which creeps rapidly riverward when saturated with water.
