Abstract
The Paderborn 7.5-minute Quadrangle (fig. 1) is located about 5 miles east of bluffs that overlook the Mississippi River valley. Highest elevations on the west, supported by the Waterloo-Dupo Anticline (Nelson 1995), descend east-ward to the wide Prairie du Long valley, a tributary to the Kaskaskia River. The margins of the Illinois and pre-Illinois Episode glaciations lie only a few miles west. The city of Waterloo, the largest town in the area (population 7,614; State of Illinois 2000), is centered about 1 mile west of the map margin. The main land use is agriculture. The Waterloo Mine (limestone) is the physically largest industry. Future residential development is expected because of the pictur-esque rural setting immediately on the outskirts of Belleville, and the ready access to St. Louis by highway and light rail. Figure 1 Shaded relief map of the St. Louis Metro East area (southern portion). The Paderborn Quadrangle is outlined in yellow. Pink arrows indicate approximate ice flow direction during the Illinois Episode. The prominent ridge trending south-southeast–north-northwest through Waterloo is the axis of the Waterloo-Dupo Anticline. Sharp ridges immediately west of the Kaskaskia River valley are a moraine complex.
