The icy waters of the Cook Inlet, right, are contrasted by the slopes of the Aleutian Range, Alaska, left. Just left of center, a white patch shows the peak of Mount Redoubt, an active volcano and the highest peak in the Aleutian Range.

It is located in the Chigmit Mountains (a subrange of the Aleutians), about 180 km (110 miles) southwest of Anchorage, Alaska. Mount Redoubt, also known as Redoubt Volcano, erupted in 1902, 1966,1989 and again in 2008.

Mount Redoubt is not a particularly steep peak, but it is a massive mountain: it rises 9,000 feet (2,700 m) above the surrounding valleys to the north, south, and southeast in little over 5 miles (8 km).

East of the volcano lies the Cook Inlet, or Nuti, which provides navigable access to the port of Anchorage at the northern end, and to the smaller Homer port further south.

It is a large estuary stretching 180 miles from the Gulf of Alaska to Anchorage in south-central Alaska. It separates the Kenai Peninsula from mainland Alaska and branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage.

The watershed covers about 100,000 kmĀ² 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.
