USA - March 11th, 2012

Multiple cities can be observed along the eastern coast of the United States of American in this image, appearing as grey areas (best observed upon opening the full image). From the upper right, moving southwestward near the shoreline, one can see Boston, Massachusetts; Providence, Rhode Island; New York City, New York; Trenton, New Jersey; Philadelphia, Pennsylvania; Baltimore, Maryland; and Washington, D.C.

Visible further east are the Appalachian Mountains. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west. These alternating ridgelines and valley appear as alternating lines of brown and green, respectively.

The bright white area in the upper part of this orthorectified wide-swath ASAR image is Philadelphia, the largest city in the Commonwealth of Pennsylvania. The city is located in the Northeastern United States along the Delaware and Schuylkill rivers. It is the fifth-most-populous city in the United States, with a population of 1,526,006 as of the 2010 U.S. Census.

According to the United States Census Bureau, the city has a total area of 142.6 square miles (369.3 km2), of which 135.1 square miles (349.9 km2) is land and 7.6 square miles (19.7 km2), or 5.29%, is water. Bodies of water include the Delaware and Schuylkill Rivers, and Cobbs, Wissahickon, and Pennypack Creeks. The lowest point is sea level, while the highest point is in Chestnut Hill, at approximately 445 feet (136 m) above sea level (near the intersection of Germantown Avenue and Bethlehem Pike).

Visible to the south of the city is Delaware Bay, a major estuary outlet of the Delaware River on the Northeast seaboard of the United States whose fresh water mixes for many miles with the waters of the Atlantic Ocean. It has an area of 782 square miles. The bay is bordered by the State of New Jersey and the State of Delaware. The shores of the bay are largely composed of salt marshes and mud flats, which appear white in this image, with only small communities inhabiting the shore of the lower bay.

A massive snow storm fell on the East Coast Friday and Saturday, and some areas have had record snow accumulation totals over the past two days. The East Coast snow storm shut down airports, highways, and transit systems, and left tens of thousands of people without electricity.

This snowfall broke many longstanding records. Saturday, a record snowfall total of 16 inches was reported at Washington Dulles airport, which broke an old record of 10.6, set December 12, 1964. Reagan National airport also reported a record breaking snow fall of 13.3 inches Saturday, surpassing the old record of 11.5 inches set on December 17, 1932.

The Philadelphia airport received 22.9 inches in snowfall totals since Friday, and Colora, Maryland received 17.2 inches of snow fall.

The state of New Jersey reported snow fall in the following areas: New Brunswick 11.1 inches, Pottersville 7.8 inches, Cape May 6.2 inches, and Midland Park 5.7 inches. The state of Delaware reported snow fall totals in the following areas (in inches): Blackbird 17.7, New Castle airport 17, Dover 16.2, and in Wilmington 14.

The waters of Lake Erie (below) are clouded by tan sediments, particularly along the upper shoreline to the left, while those of Lake Ontario (above) are much clearer with the exception of a small stretch along the southern shore.

Lake Erie is the fourth largest lake (by surface area) of the five Great Lakes in North America. It is the southernmost, shallowest, and smallest by volume of the Great Lakes, and therefore also has the shortest average water residence time. Lake Erie drains via the Niagara River and Niagara Falls into Lake Ontario.

It is bounded on the north by the Canadian province of Ontario, on the south by the U.S. states of Ohio, Pennsylvania, and New York, and on the west by the state of Michigan.
