The Rocky Mountains

The Rocky Mountains, often referred to as the Rockies, are a major mountain range in western North America. They stretch more than 3,000 miles from northern British Columbia in Canada to New Mexico in the United States.

Formation of the Rockies

The Rockies were formed through a series of geological events over millions of years. The mountain range began to form during the Laramide orogeny, a period of mountain-building activity that occurred between 80 and 55 million years ago. The collision of the North American Plate and the Pacific Plate caused the Earth's crust to buckle and uplift, creating the Rocky Mountains.

Geography and Features

The Rockies are known for their rugged terrain, diverse ecosystems, and numerous peaks exceeding 14,000 feet in elevation, known as "fourteeners." Notable national parks located within the Rockies include Yellowstone, Rocky Mountain, Grand Teton, and Glacier. The range also serves as a crucial watershed, with numerous rivers and streams originating from its snow-capped peaks.

Wildlife and Biodiversity

The Rockies are home to a wide variety of flora and fauna, including iconic species such as grizzly bears, mountain lions, bighorn sheep, and elk. The diverse ecosystems within the Rockies support a rich array of plant life, from alpine meadows to dense coniferous forests.

Human Impact

Native American tribes, including the Shoshone, Blackfeet, and Ute, have long inhabited the region, utilizing its resources for sustenance and cultural practices. European exploration and settlement in the 18th and 19th centuries led to the exploitation of natural resources such as minerals, timber, and water, impacting the landscape and indigenous communities.
