Physical Features of Idaho
Idaho is characterized by rugged mountains, deep river canyons, and broad forested valleys. Much of the state is dominated by the Rocky Mountains, with numerous ranges and wilderness areas covering central and northern Idaho. The Snake River Plain stretches across the southern region, forming a wide, relatively flat agricultural area. Major rivers such as the Snake and Salmon carve through steep terrain, creating dramatic landscapes including Hells Canyon, one of the deepest river gorges in North America.
