An elevation is a measurement attached to a point and a vertical reference. Elbrus has two principal summit cones, so even a precise-looking height needs to identify its summit. The Global Volcanism Program lists 5,642 m for Elbrus West and 5,621 m for Elbrus East.[1]
Different mapping products can use different surveys, datums, resolutions or publication dates. A reference page should cite the source rather than treating a height as detached from method. The same rule applies to coordinates, glacier area and map boundaries.
Height alone does not settle a continental ranking. That conclusion also depends on a chosen Europe–Asia boundary convention; see Europe and Asia. For the mountain’s summit structure see The two summits.
