St. Lawrence Island - Geography

Geography

The United States Census Bureau defines St. Lawrence Island as Block Group 6, Census Tract 1 of Nome Census Area, Alaska. As of the 2000 census there were 1,292 people living on a land area of 1,791.56 sq mi (4,640.1 km2). The island is about 90 miles (140 km) long and 8–22 miles (13–36 km) wide. The island has no trees, and the only woody plants are Arctic Willow, standing no more than a foot (30 cm) high.

The island's abundance of seabirds and marine mammals is due largely to the influence of the Anadyr Current, an ocean current which brings cold, nutrient-rich water from the deep waters of the Bering Sea shelf edge.

To the south of the island is a persistent polynya, formed when the prevailing winds from the north and east blow the migrating ice away from the coast.

Famous quotes containing the word geography:

    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)

    The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.
    Rutherford Birchard Hayes (1822–1893)

    Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.
    Ralph Waldo Emerson (1803–1882)
