Elevation Map of Idaho

This Idaho topographic elevation map shows the Gem State in 24 terraced elevation bands. The scale runs from 216 meters (709 ft) up to 3,861 meters (12,667 ft). Each band steps through the relief in sequence, so the map reads like a physical relief model. Lowlands appear in deep greens, middle elevations warm into golds and reds, and the highest terrain fades into grays and whites.

Idaho covers about 216,443 square kilometers (83,568 sq mi). The Snake River Plain sweeps a smooth crescent through the jagged central mountains, and the contrast makes this one of the most striking relief maps in the series.

Highest Point in Idaho

Borah Peak, at 12,667 ft (3,861 m), is the highest point in Idaho. On this topographic map, it anchors the pale summit end of the elevation scale.

Lowest Point in Idaho

The lowest point in Idaho is the Snake River at Lewiston, at an elevation of 709 ft (216 m). On the relief map, this terrain fills the deep green base of the color scale.

Idaho Map Datasets

I prepared this relief map with elevation data from the AWS Terrain Tiles dataset. The dataset builds on the NASA Shuttle Radar Topography Mission (SRTM) along with other open topographic sources, and it serves global elevation data as map tiles that anyone can access.

The map spaces its 24 elevation bands with a blend of two methods. Half of the spacing follows equal elevation steps. The other half follows equal land area, a technique known as histogram equalization.

Why blend them?

A fixed interval scale would leave flatter regions sitting in a single color, which hides their topography. On the other hand, full histogram equalization would push a quarter of the land into summit tones. The blend lets this elevation map use the entire relief palette while the legend stays honest. Each label marks the true elevation behind its band, which is why the values are not evenly spaced.
