The flute theory describes the formation of the spindle-shaped type of these objects, and Boulton's hypothesis states the more common variety is formed by the erosional streamlining of rock obstacles.
According to Chorley, their maximum width is located approximately three- tenths of the distance from their most distinctive feature. The flute theory describes the formation of the spindle-shaped type of these objects, and Boulton's hypothesis states the more common variety is formed by the erosional streamlining of rock obstacles. These objects can cluster to form a swarm, the largest one of which is found in west-central New York. Often arranged in belts, these objects feature a tapered end that points in the direction of glacier advance. For 10 points, name these tear-shaped elongated hills of unstratified glacial drift.
