North Polar Regions
The North Polar Regions of Ivory are dark, cold, and heavily cratered. A thin cover of frost and ice lies across the highest latitudes, especially along the polar rim and within colder depressions, but most of the underlying terrain remains exposed. Large impact basins, crater chains, worn rims, and rough ejecta fields dominate the surface. The polar frost brightens the margins without concealing the moon’s battered topography.
The northern hemisphere preserves some of the oldest visible terrain on Ivory. Broad crater floors lie beside broken uplands and irregular scarps, while smaller impacts are scattered across nearly every exposed surface. The low albedo of the moon gives much of the north a muted charcoal and brown-grey tone, with the brighter polar deposits confined to limited zones of cold-trapped frost.
Equatorial Regions
The Equatorial Regions of Ivory are dominated by dark cratered plains, immense impact basins, and broad stretches of exposed rocky ground. Several very large circular basins define the equatorial belt, many with smoother, darker floors set inside sharply preserved rims. Between them lie dense fields of smaller craters, overlapping ejecta blankets, and rough highland belts broken by fractures and degraded escarpments.
This is the most varied part of the moon’s surface. Some sectors consist of relatively smooth plains marked by later impacts, while others are more broken and uneven, with clustered craters and irregular ridges cutting across older basin margins. The equatorial terrain is dry, airless, and geologically inert at the surface, with its present form set by repeated bombardment and long preservation under cold conditions. The low reflectivity of Ivory is especially evident here, where darker regolith and shadowed basin floors dominate much of the landscape.
Southern Polar Regions
The Southern Polar Regions of Ivory are brighter than much of the equator, with frost and ice spread more broadly across the highest latitudes and along cold-trapping depressions. A pale southern cap extends over the polar margin, collecting in crater floors, low basins, and sheltered hollows. Even with this brighter cover, the underlying terrain remains clearly visible, including large worn craters, rough basin edges, and broken upland surfaces.
The south preserves the same ancient impact-scarred character seen elsewhere on the moon, but with a stronger contrast between dark exposed ground and lighter frost deposits. Large circular depressions remain common, and several broad basins continue across the lower southern latitudes before merging into the frost-brightened polar zone. The result is a cold and stable southern hemisphere shaped by cratering, regolith accumulation, and persistent polar frost rather than by active surface change.
