Landscape
Bounded by rolling hills, bluffs, farmland, and woods in its upper reaches, dammed by H.M. Byllesby in 1910 for hydroelectric power to create Lake Byllesby Reservoir, the Cannon enters a broad gorge below Cannon Falls, where it is flanked by bluffs up to 300 feet (100 m) high. The Cannon River is underlaid with a variety of sedimentary rocks. The river valley created by cutting through these rocks produced rock outcrops of St. Peter Sandstone, the Prairie du Chien Group of dolomites and sandstone, and near the river's mouth, Jordan Sandstone and the St. Lawrence and Franconia formations.
Past the Falls, the river is in the Driftless Area of Minnesota, a region that remained ice free during the last ice age, allowing the river to carve a very impressive canyon. The upper region of the river is involved with terminal moraines and glacial drift and till, and is not in the Driftless Area.

Famous quotes containing the word landscape:
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
