The glacier was God's great plough set at work ages ago to grind, furrow, and knead over, as it were, the surface of the earth.
Louis Agassiz. Swiss biologist and geologist. 1807-1873

These gently rolling slopes, awaiting man's plough, are kames dating from the last ice age, mounds of sand, gravel and till that accumulated in a depression on a retreating glacier, and then deposited on the land surface when the glacier melted.
