Rock Island County

Rock Island County was mapped by the late Dr. Richard Anderson, Augustana College, over a period of several years. Barbara Stiff, ISGS, created a digital compilation from Anderson's 1:24,000-scale field maps. This county map compilation will be added to the ISGS mapping database and made available through this Web site in the future. Until that time, please contact Barbara Stiff for more information.
