Two rivers traverse this rich farming and livestock region—the more northeasterly Wapsipinicon River and the larger Cedar River, on which are situated the twin cities of Cedar Falls and Waterloo (midway between left center and center). Waterloo, the larger and more easterly of the twin cities, is an industrial and trade center specializing in farm machinery and air conditioning equipment. Cedar Falls has a diversity of small manufacturing industries and is the home of Northern Iowa University.
