Planum Boreum
Planum Boreum (Latin: "the northern plain") is the northern polar plain on Mars. It extends northward from roughly 80°N and is centered at . Surrounding the high polar plain is a flat and featureless lowland plain called Vastitas Borealis which extends for approximately 1500 kilometres southwards, dominating the northern hemisphere.
Features.
The main feature of the Planum Boreum is a large fissure or canyon in the polar ice cap called Chasma Boreale. It is up to wide and features scarps up to high
its age is Middle to Late Amazonian. The Olympia Undae unit may have formed during early denudation incidents of the Planum Boreum Cavi unit in its immediate neighbourhood. More distant dune fields from the Planum Boreum Cavi unit, such as Siton, Aspledon, and a large portion of Olympia Undae may have formed during earlier erosional events of the Planum Boreum Cavi unit. Other sources to these dune fields may include Rupes Tenuis, although this source is now considered to be exhausted.
