Aquifers in melt-water channels along the southwest flank of the Des Moines Lobe, Lyon County, Minnesota Aquifers in melt-water channels along the southwest flank of the Des Moines Lobe, Lyon County, Minnesota

The valley, which heads in the Laurentian Divide, and covers about 120 square miles, coincides approximately with a bedrock valley filled with as much as 150 feet of glacial deposits.

The stoneroller, Campostoma anomalum (Rafinesque), in Great Smoky Mountains National Park The stoneroller, Campostoma anomalum (Rafinesque), in Great Smoky Mountains National Park

The stoneroller (Campostoma anomalum) is one of the more important fish in Great Smoky Mountains National Park because of its abundance and habits. Although esteemed locally as a food and a bait fish, the stoneroller is exploited but little since the fishing regulations which govern the utilization of game fishes afford it a large measure of protection. Distribution is controlled by...
