The Brooks Range extends about 600 miles (1,000 km) in an east-west direction across Alaska from the U.S. border with Canada’s Yukon territory to the Chukchi Sea, and it reaches widths of up to 200 miles (300 km).
Alaskan mountains, three principal mountain groups of far northwestern North America—the Brooks Range , Alaska Range, and Aleutian Range —found in the U.S. state of Alaska. The mountain ranges of Alaska give their state a rugged and beautiful terrain across its entire expanse.
Diameter: East to west, 2,400 miles; north to south, 1,420 miles. Coastline: 6,640 miles, point to point; as measured on the most detailed maps available, including islands, Alaska has 33,904 miles of shoreline.
Myth: Arctic Alaska ( Utqiagvik (Barrow), Prudhoe Bay, Kaktovik) is the coldest part of the state. Fact: The Northern Interior (along Brooks Range ) holds the record for the lowest temperature, where the mercury fell to -79.8° F (-62° C) at Prospect Creek in 1971.
“When it comes to wildlife, Alaska is famous for salmon, moose, caribou, bears, whales, bison, puffins, jellyfish, etc. When it comes to scenery, Alaska is famous for glaciers and fjords, mountains, and more lakes, rivers, and waterways than one could dream of.

The Rockies do not extend into the Yukon or Alaska , or into central British Columbia. Other mountain ranges continue beyond the Liard River, including the Selwyn Mountains in Yukon, the Brooks Range in Alaska , but those are not part of the Rockies , though they are part of the American Cordillera.
Generally, the ranges included in the Rockies stretch from northern Alberta and British Columbia southward to New Mexico , a distance of some 3,000 miles (4,800 km). In places the system is 300 or more miles wide.

In 1980, momentum continued to favor the name Denali after the Alaska National Interest Lands Conservation Act changed the park’s name to Denali National Park and Preserve. But the official name of the mountain remained Mount McKinley .
Sixty million years ago, tectonic uplift pushed Earth’s crust upward, forming Denali and the other Alaska Range mountains. Denali is the centerpiece of the Denali National Park and Preserve, which spans 2.4 million hectares (6 million acres) of land.
