Image of the Iapygia Quadrangle (MC-21). Most of the region contains heavily cratered and dissected highlands. The west-central part contains Huygens crater. The southern one-third includes the northern rim of the Hellas basin.

The Iapygia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Iapygia quadrangle is also referred to as MC-21 (Mars Chart-21).[1] It was named after the heel of the boot of Italy. That name was given by the Greeks[2] It is part of a region of Italy named Apulia.[3][circular reference] The name Iapygia was approved in 1958.[4]

The Iapygia quadrangle covers the area from 270° to 315° west longitude and from 0° to 30° south latitude on Mars. Parts of the regions Tyrrhena Terra and Terra Sabaea are found in this quadrangle. The largest crater in this quadrangle is Huygens. Some interesting features in this quadrangle are dikes.[5] the many layers found in Terby crater, and the presence of carbonates on the rim of Huygens crater.[6]
