Intermountain West, Geographic region in Western United States.
The Intermountain West is a large geographic area between the Rocky Mountains to the east and the Cascade Range and Sierra Nevada to the west. This region contains varied terrain including high plateaus, deep canyons, and numerous mountain peaks spread across multiple climate zones.
Indigenous peoples inhabited this land for thousands of years before European settlement began in the 1800s, bringing dramatic changes to the region's economy and structure. Mining and railroad development that followed further reshaped the landscape and communities throughout the area.
Native American heritage remains visible in local arts, place names, and celebrations that blend with later settler traditions throughout the region.
This vast region is best explored by car or air travel since distances between attractions are considerable and spread across multiple states. Outdoor activities like hiking are available year-round in lower areas, though winter conditions in higher elevations may limit some trails.
The region holds one of the highest concentrations of national parks and protected wilderness areas in the country, each preserving distinct landscapes and ecosystems. This clustering makes it a major hub for conservation work and outdoor research.
