ABSTRACT William Maclure, Father of North American Geology, partnered with Robert Owen in 1825 to establish an experimental socialistic community focusing on equitable reform in New Harmony, Indiana, USA. Artists, educators, and natural scientists recruited from Philadelphia arrived on a keel boat named Philanthropist in January 1826. Upon their arrival, Maclure established the New Harmony schools using a modified Pestalozzian educational approach under the guidance of Madame Fretageot. The New Harmony schools focused on practical education through direct observation of nature as well as a curriculum involving drawing, music, science, writing, and trade skills such as carpentry, engraving, and printing. Furthermore, the integration of arts and sciences with hands-on experiences led to a productive community of natural scientists who published significant works on the conchology, geology, ichthyology, and paleontology of North America. In the mid-nineteenth century, hand-drawn illustrations were reproduced through engravings, etchings, or lithography prior to the invention of the daguerreotype process in 1839, collodion wet plate process in 1851, and flexible celluloid film in 1888. In particular, the published works of David Dale Owen demonstrate the increasing importance of evolving reproduction techniques to paleontological illustration as well as the significance of hand-drawn artistic renderings. Interestingly, the modified Pestalozzian educational approach introduced by Maclure in New Harmony has several implications for the modern classroom. For instance, recent studies suggest that drawing improves spatial reasoning skills and increases comprehension of complex scientific principles. Likewise, engaging students in the drawing of fossils delivers a meaningful learning experience in the paleontology classroom.

ABSTRACT The last-glacial megaflood Kankakee Torrent streamlined hills and the remarkably straight backslope of the Kalamazoo moraine (Lake Michigan lobe of the Laurentide ice sheet) in southwestern Michigan. Flooding ensued as proglacial Lake Dowagiac overflowed across remnants of the Lake Michigan lobe at the position of the inner margin of the Kalamazoo moraine as glacial debris and ablating ice were pinned against Portage Prairie. Proglacial Lake Dowagiac developed in the Dowagiac River valley as the lobe retreated to form the Valparaiso moraine. A minimum age of the Kankakee Torrent (18.7 ± 0.6 k.y. B.P) is indicated by the weighted mean value of six optically stimulated luminescence ages determined from quartz sand in glaciofluvial sediment on the Kalamazoo moraine (Lake Michigan and Saginaw lobes). This value is consistent with tighter age control based on radiocarbon ages of tundra plants within silty sediment forming ice-walled lake plains and in a torrent-scoured lake basin (Oswego channel) in Illinois. Crosscutting relationships of well-dated moraines indicate the Kankakee Torrent occurred sometime between 19.7 and 18.9 calibrated (cal.) k.y. B.P. as it skirted the south margin of the Valparaiso Morainic System.
