USA – September 17th, 2012

Smoke from fires near the Oregon-Washington border can be observed blowing in a generally westerly direction in this image (click here for previous images of fires in western USA). The border is marked by the Columbia River, visible crossing the upper half of the image more or less horizontally. The largest fire near the river in Washington State is the Cascade Creek Fire, which has burned 6,467 acres.

The white area in the upper part of this orthorectified image comprises the cities of Longview and Kelso in Washington State, USA. Longview is located in southwestern Washington, at the junction of the Cowlitz and Columbia Rivers.

The Cowlitz River is a tributary of the Columbia River. It has a 2,586-square-mile (6,698 km2) drainage basin, located between the Cascade Range and the cities of Kelso and Longview. The river is roughly 105 miles (169 km) long, not counting tributaries.

Mount Hood, standing out above the surrounding peaks of the Cascade Range in the lower right quadrant of this orthorectified image, is a stratovolcano in the Cascade Volcanic Arc of northern Oregon. It is located about 50 miles (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties.

The exact height assigned to Mount Hood’s snow-covered peak has varied over its history. Modern sources point to different heights: 11,249 feet (3,429 m) based on the 1991 U.S. National Geodetic Survey and 11,240 feet (3,426 m) based on a 1993 scientific expedition. Regardless, it is the highest mountain in Oregon and the fourth-highest in the Cascade Range.

Visible to the north of the volcano is Lake Bonneville, a reservoir on the Columbia River shared by the U.S. states of Oregon (south) and Washington (north). It was created in 1937 with the construction of Bonneville Dam. The reservoir stretches between it and the Dalles Dam, upstream. It lies in parts of three counties in Oregon (Multnomah, Hood River, Wasco) and two in Washington (Skamania, Klickitat).

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.
