Environmental Factors Influencing Prehistoric Site Selection Along The Portage River, A Tributary Of The St. Joseph River, Southwest Michigan, Timothy D. Knapp
Masters Theses
This study examines the environmental factors influencing the location of prehistoric sites within the Portage River drainage. Over 100 sites recorded during four seasons of archaeological survey are examined applying the following environmental variables: type of glacial deposit, glacial landform, soil, distance to the nearest source of water, distance to the nearest ponded water, and vegetation zones occurring within 100, 500, and 1000 meters. Site locations are then statistically compared with the location of 100 randomly generated loci within the study area.
The findings of this research indicate that sites are non-randomly located with respect to certain environmental variables. Sites …

The First Documentation Of A Lower Middle Pennsylvanian Upland Flora From The Eastern Margin Of The Eastern Interior Basin (Illinois Basin), Vicki J. Comer
Masters Theses
The primary objective of this study is to reconstruct the paleofloristics of an unnamed shale of lower Middle Pennsylvanian age. The shale is periodically exposed in the highwall of the Ashboro Pit, Log Cabin Coal Company, Clay County, Indiana. This will be the first upland fossil flora to be described from the eastern margin of the Eastern Interior Basin (Illinois Basin). The gray shale containing the upland flora lies directly above the Upper Block Coal (SW 1/4, SE 1/4, sec. 17, T. 11N., R. 6W.)
Two collections, collected on three different occasions were made available for analysis: Smithsonian Natural …
