A plateau where the layers read like tree rings of climate.
Planum Chronium is a southern high-latitude plateau lying near the Martian polar cap, where layered deposits preserve a record of climate change. Its stacked strata act like pages archiving cycles of ice, dust and shifting seasons over long spans of time.

Each layer was laid down under different atmospheric conditions, so the sequence records swings in Mars' climate driven by changes in its tilt and orbit.
To scientists, terrain like this is a natural archive: reading the layers is like counting the rings of a tree, revealing when the planet was icier or dustier. It makes Planum Chronium a quiet but scientifically rich corner of the polar south.
Planum Chronium's layers echo the great south polar layered deposits, extending Mars' climate record out into the surrounding plateaus.
