The following table lists those positive topographic structures (mountains, plateaus, shield volcanoes, and layered plains) that have been given names by the International Astronomical Union. Coordinates and Length come from the USGS website that hosts that nomenclature list. Height information from Paul Schenk's 2001 paper, The mountains of Io: Global and geological perspectives from Voyager and Galileo. When the name refers to multiple mountains, the tallest peak from Schenk et al. 2001 is listed. Those whose heights come from another sources are noted and sourced in the table. Height ranges result from uncertainties due to different methods used to determine the height of the mountain.
