ABSTRACT The historic town of New Harmony is located along the Wabash River in Posey County, Indiana, and served as a focal point for natural scientists, especially geologists, in the early nineteenth century. Notable geologists that lived and worked in New Harmony during this time include Edward Travers Cox, William Maclure, Fielding Bradford Meek, Joseph Granville Norwood, David Dale Owen, Richard Dale Owen, Benjamin Franklin Shumard, Gerard Troost, and Amos Henry Worthen. Other natural scientists who worked in New Harmony include Charles Alexandre Lesueur and Thomas Say, and the town was also visited by James Hall, Leo Lesquereux, Sir Charles Lyell, and Alexander Philipp Maximilian, Prince of Wied. The purpose of this field-trip guide is to highlight the scientific and geologic enterprise that operated in nineteenth-century New Harmony, Indiana. There will be a tour of historic buildings including laboratories used by David Dale Owen, such as the Rapp-Owen Granary and his fourth laboratory, which was constructed in 1859. Furthermore, field-trip participants will visit a new geology exhibit at the Working Men’s Institute, an organization established by William Maclure in 1838. The field excursion will also visit historically significant localities, including Mississippian and Pennsylvanian exposures, the type section of the West Franklin Limestone, and a Pennsylvanian paleobotanical site that yielded extensive collections of plant fossils in the mid-nineteenth century. Finally, this field trip will provide an opportunity to discuss the importance of art to geological studies in the early nineteenth century. Specifically, hand-colored geologic maps, cross sections, and renderings of fossils were included with many of the scientific reports of historic New Harmony, and are reflected by the superb artwork of Charles Alexandre Lesueur, David Dale Owen, and Thomas Say. Access to view their original scientific artwork is possible only through special arrangement with the Working Men’s Institute.

Abstract The purposes of this trip are to assist in interpreting the complexities of Pennsylvanian stratigraphy and sedimentation and to collect representative conodonts. The first stop is the West Franklin Limestone Member of the Shelburn Formation, which represents the Desmoinesian-Missourian boundary and the second is the Atokan Lead Creek Limestone Member of the Mansfield Formation. To help provide a general overview of the somewhat repetitive Pennsylvanian rock sequences in southwestern Indiana, we will visit two coal mines, each displaying several hundred feet of Desmoinesian rocks. We will be able to collect conodonts at all stops except Stop 3.

Abstract The Cataract Lake emergency spillway in Putnam County, Indiana, is in the SW¼NW¼ Sec.13, T.12N., R.5W. (Poland Quadrangle). The spillway cut is most easily reached by following the secondary road indicated in Figure 1 north from Indiana 42, a distance of about 2 mi (3.2 km). The secondary road thatleads to the spillway cut is identified by a Corps of Engineers sign that points the way to the reservoir dam. The intersection of Indiana 42 with the road to the spillway is about 5 mi (8 km) south of 1-70 and is 1.8 mi (3 km) east of Poland, Indiana, and 4.6 mi (7.4 km) west of the intersection of Indiana 243 and Indiana 42 (Fig. 1). The spillway cut is immediately adjacent to the secondary road that runs north from Indiana 42. Because the spillway cut is a restricted area, permission to enter should be obtained at the Corps of Engineers office just north of the dam.

Abstract The field is located at the juncture of Pike, Gibson, and Warrick counties, Indiana, where the surface formations are of Pennsylvanian age. The regional dip amounts to 35 feet per mile to the southwest, and the collecting structures are mere pimples upon the regional slope. Surface structure does not coincide with subsurface dips, the lime-stone outcropping in the field showing production coming from a syncline. The oil sand manifests evidences of lens-like accumulation and may be responsible for the arching of the overlying rocks. The Oakland City sand or the Mooretown sandstone forms the reservoir for petroleum. Gas is entirely lacking; each well had to be shot and put on a pump to secure production. Water is almost a negligible quantity, and the amount handled with the oil is decreasing. The crude is of good quality, green to brown in color, and fairly high in gasoline content. Production is light; consequently development has been slow.
