DC from space


An astronaut aboard the International Space Station took this photograph (5-meter spatial resolution) of Washington, the capital of the United States of America. Here the Potomac River flows south toward Chesapeake Bay and forms the geographic boundary between Virginia and Washington (as well as Maryland), while the Anacostia River links to the Potomac on the eastern side of the city.
Wedged between Maryland and Virginia, the District of Columbia was established in 1790 to serve as the permanent seat of the U.S. federal government. Originally the territory was relinquished by Virginia and Maryland as a 100-square-mile plot on both sides of the Potomac River. At the time, Georgetown, Maryland, and Alexandria, Virginia (just out of the scene to the lower left), were successful ports located on the eastern and western sides of the river. Georgetown remains as an historic neighborhood of Washington, D.C. In 1846, Virginia gained back the land contributed to the District of Columbia as a result of neglect of the area by Congress (known as retrocession). Those areas eventually became the cities of Arlington and Alexandria. There are 40 boundary stones that mark the original District boundary and stand as the oldest federal monument in the country.

  1. It was a swamp, you know...when it they laid it out and when they started building.

    It's still a swamp.

    1. Hopefully we'll have a few years to drain that festering miasma.

  2. A 600 meter X 600 meter nickel Iron asteroid striking at 30 meters per second would make a crater aprox. 5x5 kilometers wide and 1000 to 2000 meters deep, and generate enough energy to vaporize every living thing within 200 kilometers of the impact crater.----Just sayin'----Ray
