AbstractThick Roxana Silt (middle Wisconsinan) in central and southwestern Illinois traditionally has been interpreted as loess derived from valley-train deposits in the ancient Mississippi River valley. Winters et al. (H. A. Winters, J. J. Alford, and R. L. Rieck, Quaternary Research 29, 25–35, 1988) recently suggested that the Roxana was not directly related to glacial activity, but was derived from sediment produced by increased shoreline and spillway erosion associated with a fluctuating ancestral Lake Michigan. Because (1) paleoenvironmental and paleohydrologic conditions inferred in the hypothesis are unlikely for a loess depositional system and (2) loess did not accumulate during late Wisconsinan deglaciation under conditions similar to those hypothesized, we suggest the hypothesis should be rejected. Roxana distribution suggests the major source was drainage from the upper Mississippi River valley, and variations in loess thickness in Illinois can be explained by consideration of valley width, depth, orientation, and postdepositional erosion. Tills in the headwaters region of the ancient Mississippi drainage system in Minnesota and Wisconsin occur in the appropriate stratigraphic position and have colors and mineralogic compositions that suggest they could be the parent till of the Roxana. We believe a valley-train source for thick Roxana is most probable and urge continued consideration of middle Wisconsinan glaciation in the upper Great Lakes area.

Native Peoples

Abstract This essay recognizes the totality of practices by which Native peoples of the upper Mississippi River valley for centuries oriented themselves to place as an Indigenous map. After limning the map and its material and nonmaterial components, I then place it at the center of a comparative Indigenous-colonizer literary analysis and argue that the manuscript of Euro-American Jonathan Carver’s 1760s travel narrative written in the region is in constitutive relationship to the map. I conclude by turning to printed versions of his narrative to consider how they extend and shape colonialist orientations to the Indigenous map. Attending to how the land has been shaped in partnership with Indigenous text making transforms American literary studies by demonstrating one way that Euro-American texts always were, are, and will be in relation to Native genres.
