University of Nebraska-Lincoln: Google find expands understanding of Nebraska’s icy past

University of Nebraska-Lincoln: Google find expands understanding of Nebraska’s icy past. “By analyzing Google Earth images, a trio of Conservation and Survey Division scientists discovered that permafrost was common in northern Nebraska about 26,500 to 19,000 years ago when ice sheets were last at their greatest extent across North America. The discovery adds another dimension to the study of changing climates in Nebraska and the surrounding Great Plains, said Matt Joeckel, director of the Conservation and Survey Division and co-author on the study, which published in the fall edition of Great Plains Research.”
