Fort Wayne, Indiana

Abstract The geology displayed in and around the city of Fort Wayne, Indiana, is interesting and critically important for at least two reasons: (1) a large quarry near the city exposes an unusual variety of Paleozoic strata, some facies of which are not exposed at any other place; and (2) the city is situated at the junction of several Pleistocene glacial features of regional significance (Fig.1). The largest and most spectacular quarry in northeastern Indiana is the Ardmore Avenue Quarry of May Stone and Sand, Inc., located along Ardmore Avenue in the NE¼Sec.29, T30N., R.12E. on the southwest edge of Fort Wayne (Figs.1), 2). This quarry is one of the two largest and deepest crushed-stone quarries in Indiana, measuring more than 2,000 ft (610 m) across in a northeast-southwest direction and about 271 ft (82 m) deep during the fall of 1983 (Fig.3). The quarry is readily accessible for public viewing from a stand provided by the company on the north side of the quarry. Thisstand allows such an instructive and spectacular view of the quarry that it has become the focal point for most field trips to the area. Those desiring to enter the quarry should direct their inquiries to the Ardmore Avenue office of May Stone and Sand, Inc. The Ardmore Avenue Quarry is also the focal point for the study of Pleistocene features in this area because of the excellent exposures of a complex Pleistocene section at the top of
