Mount Saint Elias: terrain elevation and local relief
Mount Saint Elias uses an approximately 5,465-meter surface estimate in EGM2008 from Copernicus GLO-30. The bounded terrain section has about 3,460 meters of local relief above its lowest sampled point. Published summit surveys are separate references.

A little more perspective
The U.S. National Park Service’s Yakutat Tlingit ethnographic reference gives Mount St. Elias as 18,008 feet, or approximately 5,489 meters. This Copernicus section reaches approximately 5,465 meters in EGM2008. The source also explains the mountain’s cultural importance; the scene is a geographic comparison, not a climbing itinerary. Icy Bay lies outside this bounded summit section, so its local-relief value does not measure the full rise from the coast.
The local-relief view subtracts the lowest sampled point in this section: 2004.9 meters at 60.287500° latitude, -141.030556° longitude. This produces about 3,460 meters of relief within the stated boundary. It is not a universal mountain base, a route’s total ascent, or topographic prominence.
The rendered surface uses the public 2021 Copernicus release, primarily based on TanDEM-X observations from 2011–2015 with infill from other sources. It is a surface model rather than a current bare-earth survey. Neutral shading explains the geometry without claiming a snow season or photographic ground texture. No datum conversion or summit correction is applied.

The 18,008-foot NPS reference is independent of the approximately 5,465-meter model. This bounded base is not sea level at Icy Bay.
