A Mid-Wisconsinan Pollen Diagram From Black Hawk County, Iowa
A pollen sequence spanning the mid-Wisconsinan Farmdalian interstadial, from 34,460 to 20,850 RCYBP (radiocarbon years before present), was recovered from a peat along a cut bank on the Wapsipinicon River in Black Hawk County, Iowa. The pollen sequence is divided into three zones. Zone I at the base...
