Accelerator mass spectrometer radiocarbon ages of the Roxana Silt (Loess) along the Upper Mississippi Valley of Wisconsin and Minnesota indicate that loess sedimentation of the Roxana Silt occurred between about 55,000 and 27,000 14C yr B.P
A new record from Potato Lake, central Arizona, details vegetation and climate changes since the mid-Wisconsin for the southern Colorado Plateau. Climatic estimates presented here are consistent with other lines of evidence suggesting a cool
and/or wet mid-Wisconsin, and a cold and/or wet late-Wisconsin climate for much of the Southwest. Potato Lake was almost completely dry during the mid-Holocene, but lake levels increased to near modern conditions by ca. 3000 yr B.P.

Parts of nine Midwestern states were ravaged by the enormous flood on the Mississippi and tributaries in 1993. It became one of the costliest natural disasters ever to strike the USA. Flood chronology, flood damage and human toll are described
In the northern part of the American Midwest where so many Europeans came as immigrants, an ethnic reawakening characterizes many urban and rural communities. Two communities are analyzed : New Glarus, Wisconsin, settled in the 1840s by Swiss people
The midden data suggest significant environmental and floristic changes in the White Mountain region. During the last 20,000 yr, cold conditions during the late Wisconsin glacial age gave way to a warm middle Holocene beginning ca. 8 000 yr B.P
