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.

Here, snow can be seen covering parts of New Jersey, Pennsylvania, Maryland, Delaware and Virginia. Offshore is another white phenomenon: the clouds are arranged in parallel lines known as cloud streets.

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 state of Virginia received more than 20 inches of snow in certain areas of the state and a state of emergency was called on Friday. The state has reported more than 3,000 car accidents and disabled cars since Friday night. A total of five people have died due to the snow storm, three of which were in Virginia.

Numerous fields, both square and circular, dot the landscape around the Columbia River as it runs through the state of Oregon, USA, in this orthorectified image. It stretches from the Canadian province of British Columbia through Washington state, forming much of the border between Washington and Oregon, before emptying into the Pacific Ocean.

The river is 1,243 miles (2,000 km) long, and its drainage basin is 258,000 square miles (670,000 km2). Measured by the volume of its flow, the Columbia is the largest river flowing into the Pacific from North America and is the fourth-largest river in the U.S.

The river’s heavy flow, and its large elevation drop over a relatively short distance, give it tremendous potential for the generation of electricity. It is the largest hydroelectric power producing river in North America with fourteen hydroelectric dams in the U.S. and Canada, and many more on various tributaries.

The Columbia has been heavily developed to serve human purposes, including dredging for navigation by larger ships; the construction of dams for power generation, irrigation, navigation, and flood control; nuclear weapons research and production; and the generation of nuclear power. These projects have come into conflict with ecological conservation numerous times, impacting fish migration and resulting in industrial pollution.

Two ranges belonging to the large Pacific Coast System are visible in northwestern North America: the Coast Mountains, upper left quadrant, and the Cascade Range, visible as a thin line of white peaks parallel to the green coastal plains.

The Cascade Range, part of the Pacific Ring of Fire, extends from southern British Columbia, Canada, through Washington state and Oregon to Northern California, USA.

It includes both non-volcanic mountains, such as the North Cascades in southern British Columbia and northern Washington, and the notable volcanoes known as the High Cascades in Washington, Oregon and northern California. Both of these divisions are visible here; the volcanic peaks of the High Cascades can be noted as a line of snow-capped summits.
