WISCONSIN AND MISSISSIPPI RIVERS

Prairie du Chien, Crawford County. August, 1970. Altitude c. 4,000 feet. The dark, almost purple waters of the Wisconsin River meet the lighter-colored Mississippi River south of Prairie du Chien. Several distributaries fan out from the Wisconsin's mouth. The delta is almost entirely covered by forest, but toward the north (left), marshland is present. Wyalusing State Park is at upper right. The Burlington Northern RR track bisects the area from upper left to lower right. A runway at the Prairie du Chien Airport is at upper left. The state of Iowa is at bottom. The camera looks up the Wisconsin River Valley to the ENE.
