Abstract
The 'Little Ice Age' was an interval between about AD 1500 and 1850, characterized by advancing glaciers in mountainous regions of Europe and western North America. However, it is unclear whether this cool moist period was truly global in extent, or how it was manifested in other regions with different climatic controls. A high-resolution reconstruction of salinity fluctuations in Devils Lake, North Dakota, based on fossil diatoms, ostracode-shell geochemistry, and bulk-carbonate geochemistry, indicates that saline conditions prevailed throughout much of the recent past. These results suggest an arid climate in the northern Great Plains throughout the 'Little Ice Age' and that during this interval climatic gradients between the Great Plains and regions to both the east and west may have been quite steep.
