What Are the Rocky Mountains Like?

The Rocky Mountains form the cordilleran backbone of western North America—a vast, rugged, and ecologically diverse range stretching over 3,000 miles (4,800 km) from northern British Columbia to New Mexico.

Scale & Topography

• Width: 70–300 miles (110–480 km) wide; comprises 100+ sub-ranges (Front Range, Sawatch, Tetons, Wind Rivers, Beartooths, etc.).
• Peaks: 100+ summits >14,000 ft (4,267 m) in Colorado alone; highest: Mount Elbert (14,440 ft / 4,401 m). Canada's Mt. Robson (12,972 ft), Wyoming's Grand Teton (13,770 ft).
• Landforms: Jagged peaks, U-shaped glacial valleys, cirques, arêtes, horns, high alpine tundra, vast coniferous forests, sagebrush steppe, red rock canyons.

Hydrology

Continental Divide runs along the crest. Headwaters of Colorado, Columbia, Missouri, Arkansas, Rio Grande, Saskatchewan, Peace, Fraser rivers—water for tens of millions.

Climate

• Highland climate: temperature drops ~3.5°F/1,000 ft.
• Long, snowy winters (200–600+ in snowfall); short, cool summers.
• Intense UV, rapid weather changes, afternoon thunderstorms.

Ecology

• Zonation: Foothills grassland → montane forest (ponderosa, Douglas-fir) → subalpine (spruce-fir) → alpine tundra.
• Wildlife: Grizzly/black bear, wolf, cougar, elk, moose, bighorn sheep, mountain goat, pika, marmot, ptarmigan, rosy-finch, cutthroat trout.

Human Significance

• Indigenous homelands (Ute, Shoshone, Blackfeet, Crow, Salish, Ktunaxa, etc.) for 12,000+ years.
• Exploration, fur trade, mining, railroads, dams, parks.
• Icons: Yellowstone, Glacier, Banff, Jasper, Rocky Mountain, Grand Teton NPs.
• Recreation: World-class hiking, climbing, skiing, fishing, hunting, photography.

The Rockies are a continent-defining wilderness corridor.
