Points of Elevation and Geographic Features

Idaho’s mean elevation is one of the largest averages in the United States. With an average altitude of 5,000 feet above sea level, Idaho is predominately mountains. The Rockies are a mountain range that pass through all of Idaho, causing a heightened elevation level throughout the state. At its lowest point, Idaho is still relatively tall, with an elevation of 710 feet above sea level. The Snake River contains the lowest point of elevation. In the opposite direction, Idaho’s tallest point of elevation is the highest tip of Borah Peak, a mountain with an elevation of 12,662 feet above sea level.

The total area of Idaho is calculated as approximately 83,642 square miles. The Gem State is 479 miles long and 305 miles wide. The ratio of land to water is an estimated 99 to 1. Of the total area, roughly 1% is water, the rest being land. This is due to Idaho’s geographic location and distance from main water sources. Unlike the other states in the Pacific Northwest, Idaho does not exist along a coastline. The main natural water resources in Idaho are rivers and lakes, with the Pend Oreille as the largest lake in the state.
