Geography
The Hennepin Canal follows a natural low area between Hennepin and Rock Island. This is actually the ancient channel of the Mississippi River, which at one time flowed from Rock Island to Hennepin, and then south through what is now the Illinois River channel. The Illinoian Stage, about 300,000 to 132,000 years before present, blocked the Mississippi River near Rock Island, diverting the Mississippi into its modern channel.

Famous quotes containing the word geography:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
