Cascade Range Crossing Washington State, USA

USA - April 8th, 2011

This image shows the northwestern part of the state of Washington, USA, near the border with Canada (above). Washington is the northwesternmost state of the contiguous United States.

Its northern border lies mostly along the 49th parallel, and then via marine boundaries through the Strait of Georgia, Haro Strait and Strait of Juan de Fuca, with the Canadian province of British Columbia to the north.

The high mountains of the Cascade Range run north-south, bisecting the state. Western Washington, west of the Cascades, has a mostly marine west coast climate with moderately mild temperatures, wet winters, and dry summers. Western Washington also supports dense forests of conifers and areas of temperate rain forest.

Junction of Cowlitz and Columbia Rivers, Washington State, USA

Canada - February 1st, 2011

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.

Hood River Between Mount Adams and Mount Hood, USA

USA - December 25th, 2010

This orthorectified image stretches from Washington State to Oregon, USA. Situated by the top edge is Mount Adams, a potentially active stratovolcano in the Cascade Range and the second-highest mountain in the U.S. state of Washington. Adams is a member of the Cascade Volcanic Arc, and is one of the arc’s largest volcanoes.

Flowing along the lower edge of the thumbnail is the Hood River, is a tributary of the Columbia River in northwestern Oregon. Approximately 25 miles (40 km) long from its mouth to its farthest headwaters on the East Fork, the river descends from wilderness areas in the Cascade Range on Mount Hood and flows through the agricultural Hood River Valley to join the Columbia River in the Columbia River Gorge.

Mount Hood, can be observed south of the river in the full image. It is a stratovolcano in the Cascade Volcanic Arc of northern Oregon. It is the highest mountain in Oregon and the fourth-highest in the Cascade Range. The peak is home to twelve glaciers.

Crater Lake in Mount Mazama Caldera, USA

USA - December 25th, 2010

This orthorectified image focuses on Mount Mazama, a destroyed stratovolcano in the Oregon part of the Cascade Volcanic Arc and the Cascade Range. The volcano’s collapsed caldera holds Crater Lake, and the entire mountain is located within Crater Lake National Park.

Mazama was destroyed by a volcanic eruption that occurred around 5,677 (± 150) BC. The eruption reduced Mazama’s approximate 14000 ft height by around a mile (1600 m). Much of the volcano fell into the volcano’s partially emptied neck and magma chamber. At 8,159 feet (2,487 m), Hillman Peak is now the highest point on the rim.

The cluster of volcanoes in the upper half of this orthorectified image are known as the Three Sisters. They are three volcanic peaks of the Cascade Volcanic Arc and the Cascade Range in Oregon, each of which exceeds 10,000 ft (3,048 m) in elevation.

The volcanoes have the third, fourth, and fifth highest peaks in the state of Oregon and are located in the Three Sisters Wilderness, about 15 mi (24 km) southwest from the nearest town of Sisters, Oregon. The three peaks have 15 named glaciers among them, nearly half of all the 35 named glaciers in Oregon.

The Three Sisters are the centerpiece of a region of closely grouped volcanic peaks which form an exception to the typical 40-mile (64 km) to 60-mile (97 km) spacing between volcanoes elsewhere in the Cascades. Nearby peaks include Belknap Crater, Broken Top and Mount Bachelor, with Three Fingered Jack and Mount Washington somewhat to the north.
