Rocky Mountain Environment: High, Cold, Wild, and Fragile

The Rocky Mountains span 3,000+ miles from New Mexico to British Columbia—a cordillera of extremes where elevation dictates everything.

Physical Template

• Elevation: 2,000–14,440 ft (Elbert); alpine zone begins ~11,000 ft.
• Continental Divide: Splits Pacific/Atlantic watersheds along the crest.
• Geology: Uplifted Precambrian cores, volcanic fields, glacial sculpture (cirques, arêtes, U-valleys).

Climate: Continental Extremes

• Winters: Long, brutal, snow-dominated (300+ inches at high elevations).
• Summers: Short, dry, intense UV (thin air), dramatic diurnal swings (40°F+).
• Precipitation: Orographic—windward slopes wet, leeward rainshadows dry.

Vegetation Zonation

• Montane: Ponderosa pine, Douglas-fir, aspen.
• Subalpine: Engelmann spruce, subalpine fir, limber pine.
• Alpine: Tundra, fellfields, cushion plants, glaciers.

Wildlife: Icons of the High Country

Elk, mule deer, moose, bighorn sheep, mountain goats, marmots, pikas, ptarmigan; predators: grizzly, black bear, cougar, wolf, lynx, golden eagle.

Human Footprint

Recreation (skiing, hiking, climbing), extraction (mining, logging), development, and climate change pressure fragile alpine systems. Conservation balances access with preservation in the "Crown of the Continent."
