Nebraska's Highest and Lowest Elevations
Topographic map of Nebraska with physiographic regions and point of highest elevation identified. Topographic data are derived from the Shuttle Radar Topography Mission (SRTM GL3) Global 90m (SRTM_GL3) (Farr, T. G., and M. Kobrick, 2000, Shuttle Radar Topography Mission produces a wealth of data. Eos Trans. AGU, 81:583-583).
Highest Elevation: Panorama Point
Panorama Point, located near the juncture of Colorado, Nebraska, and Wyoming, is the state’s highest point, with an elevation of 1655 meters (5,429 feet). Despite its name, this “point” is neither a peak nor a hill, but simply a rolling portion of the High Plains, marked only by an engraved stone and guest register.
