The Brooks Range is a mountain range that stretches from west to east across northern Alaska, USA, and into Canada’s Yukon Territory. The total length of the range is about 1100 km (700 mi), although only a section in Alaska is visible in this orthorectified image.

The mountains top out at over 2,700 m (9,000 ft). Mount Chamberlin, 9020 ft (2,749 m), is the highest peak in the range. Other notable peaks include Mount Isto, 8,975 ft (2,736 m) and Mount Michelson, 8,855 ft (2,699 m). The range is believed to be approximately 126 million years old.

Upon opening the full image, several rivers can be seen flowing down from the mountains, including the Colville River. It rises in an isolated area of the DeLong Mountains, at the western end of the Brooks Range, north of the continental divide in the southwestern corner of the National Petroleum Reserve.

The landscape of Alaska’s North Slope Borough is dotted by many lakes in this orthorectified image. The borough has a total area of 94,763 square miles (245,436 km²), of which, 88,817 square miles (230,035 km²) of it is land and 5,946 square miles (15,399 km²) of it (6.27%) is water.

Its western coastline is along the Chukchi Sea, while its eastern shores, beyond Point Barrow, are on the Beaufort Sea (visible in the top part of this image). Here, the Colville River can be seen crossing the North Slope and spilling into the Beaufort Sea.

The Colville is a major river of the Arctic Ocean coast of Alaska in the United States, approximately 350 mi (560 km) long. One of the northernmost major rivers in the North America, it drains a remote area of tundra on the north side of the Brooks Range entirely above the Arctic Circle. The river is frozen for more than half the year and floods each spring.

Upon opening the full image, the river can be seen flowing through the foothills on the north side of the Brooks Range, broadening as it receives the inflow of many tributaries that descend from the middle Brooks Range. After flowing across the Arctic plain, it enters the western Beaufort Sea in a broad delta near Nuiqsut, approximately 120 mi (190 km) west of Prudhoe Bay.

The Yukon River meanders across this orthorectified image of Denali Borough in Alaska, USA, towards Canada’s Yukon Territory, to which it lends its name. Over half of the 3,700 km (2,300 mi) long river lies in the state of Alaska, making it the longest in the state. Many lakes can be seen scattered around the river.

North of the river are the foothills of the Brooks Range, a mountain range that stretches from west to east across northern Alaska and into Canada’s Yukon Territory, a total distance of about 1100 km (700 mi). The mountains top out at over 2,700 m (9,000 ft).
