Reading - The Brooks Range: Alaska’s Last Frontier

Read the text and complete the activities below.

The Brooks Range is a magnificent mountain range stretching across northern Alaska and into Canada’s Yukon Territory. Spanning approximately 700 miles, it serves as a formidable barrier between the boreal forests of the interior and the desolate Arctic tundra to the north. Unlike many other mountain chains, the Brooks Range remains largely untouched by modern infrastructure, offering a rare glimpse into a truly wild landscape where nature dictates the rules of survival.

The ecosystem within the range is both fragile and resilient. It is home to the Western Arctic Caribou Herd, which undertakes one of the longest land migrations on Earth, moving through the rugged passes twice a year. Predators such as grizzly bears and wolves roam the vast valleys, while golden eagles soar above the jagged peaks. The vegetation is predominantly composed of low-lying shrubs, mosses, and lichens, specifically adapted to survive the long, dark winters and the brief, intense burst of the summer growing season.

Conservation efforts are central to the identity of the Brooks Range, particularly within the Gates of the Arctic National Park and Preserve. Because there are no established roads or trails, visitors must be self-sufficient and respectful of the delicate environment. However, the region faces growing challenges from global climate change, which is causing permafrost to melt and altering the migratory patterns of local wildlife. Protecting this northern frontier is essential not only for the species that live there but also as a benchmark for wilderness preservation worldwide.
