Landscape
Lake Itasca, the official source of the Mississippi River and a scenic area of northern Minnesota, has remained relatively unchanged from its natural state. Most of the area has a heavy growth of timber that includes virgin red pine, which is also Minnesota's state tree. Some of the red pine in Itasca are over 200 years old.
The Itasca terrain is sometimes referred to as "knob and kettle." The knobs are mounds of debris deposited directly by the ice near the edge of glaciers or by melt–water streams flowing on or under the glacier's surface. The kettles are depressions, usually filled with water, formed by dormant ice masses buried or partially buried under glacial debris that later melted. The retreat of the ice around 10,000 years ago left behind 157 lakes of varying size that cover 3,000 acres (12 km2) of Itasca State Park. The glaciers deposited a moraine, a combination of silt, clay, sand, and gravel that covers the landscape to a depth of around 680 feet (210 m). The park also integrates 27,500 acres (111 km2) of upland and 1,500 acres (6.1 km2) of swamp.

Famous quotes containing the word landscape:
“While the focus in the landscape of Old World cities was commonly government structures, churches, or the residences of rulers, the landscape and the skyline of American cities have boasted their hotels, department stores, office buildings, apartments, and skyscrapers. In this grandeur, Americans have expressed their Booster Pride, their hopes for visitors and new settlers, and customers, for thriving commerce and industry.”
—Daniel J. Boorstin (b. 1914)
“And year by year the landscape grow
Familiar to the stranger’s child;”
—Alfred Tennyson (1809–1892)
“When it comes, the Landscape listens—
Shadows—hold their breath—
When it goes, ‘tis like the Distance
On the look of Death—”
—Emily Dickinson (1830–1886)
