Southern Ice

~80° & N exists a Permanant H₂O Cap.

~50° & N during the Winter Season, one can find a seasonal cap of predominately CO₂ mixed with trace amounts of H₂O.

When the CO₂ sublimates in Spring, a H₂O lag follows the cap edge, subliming within days.

The Icy Regolith is a region from ~60° & N that shows frozen H₂O in the top meter of soil.

CO₂ frost condenses nightly at high elevations in the Tharsis Region

~85° & S (0° to 90° W) is the Permanent H₂O cap. It has a venier of CO₂ that remains most summers.

~45° & S during the Winter Season, the Southern Cap extends N. It is CO₂ with trace amounts of H₂O

Like the Northern Hemisphere, at ~60° & S, there exists an Icy Permafrost of frozen H₂O in the top meter of soil.
