The Kuskokwim River or Kusko River is an approximately 724 mile (1,165 km) long river in southwest Alaska. It is the ninth largest river in the United States of America, ranked by average discharge volume at its mouth; seventeenth largest by basin drainage area.

The river provides the principal drainage for an area of the remote Alaska Interior on the north and west side of the Alaska Range, flowing southwest into Kuskokwim Bay on the Bering Sea. Except for its headwaters in the mountains, the river is broad and flat for its entire course, making it a useful transportation route for many types of watercraft.

In this orthorectified image it can be seen in a more mountainous area, flowing past two buttes (center and left edge) that reach elevations of over 3000 feet.

The Cook Inlet, stretching 180 miles (290 km) from the Gulf of Alaska to Anchorage in south-central Alaska, is visible in this orthorectified image between the Alaska Range on the state’s mainland (above) and a low-laying area of the Kenai Peninsula (below).

The watershed of the Cook Inlet covers about 100,000 km² of southern Alaska, east of the Aleutian Range and south of the Alaska Range, receiving water from its tributaries the Knik River, the Little Susitna River, and the Susitna and Matanuska rivers.  Here, the mouths of several rivers and streams are visible on the northwestern shoreline, and the ASAR imagery makes it possible to observe water currents in the inlet, flowing southward.

The junction of two mountain ranges, the Alaska Range from the North and the Aleutian Range from the South, can be noted near the center of this image of Alaska, USA. Near this juncture is Lake Iliamna, dark blue, the state’s largest lake.

East of the lake and mountains is Cook Inlet, which stretches 180 mi from the Gulf of Alaska (below) to Anchorage (above) in south-central Alaska. Here, greyish-tan sediments flow from the upper reaches of the inlet down towards the gulf.

West of the Alaska Range and Lake Iliamna, on the other hand, is a flatter area of terrain. Here, the Kuskokwim River can be seen flowing southwest towards the Bering Sea. The river, which is approximately 724 miles (1,165 km) long, is also the longest river entirely contained within one state of the USA.

The Tanana River is a tributary of the Yukon River in the state of Alaska, USA. It flows in a northwesterly direction from near the border with the Yukon Territory, and laterally along the northern slope of the Alaska Range.

In the area of central Alaska visible in this orthorectified image, the river emerges into a lowland marsh region known as the Tanana Valley (left) and passes to the south of the city of Fairbanks (right). In the marsh regions it is joined by several large tributaries, including the Nenana (bottom edge) and the Kantishna.
