A closed depression inferred to be carved by melting or sublimation of ice from an ice-bearing unit.


A type of  sublimation landform.



This entry is about non-terrestrial ablation hollows.


Closely spaced depressions with similar shapes, in the residual  polar cap of Mars producing a gentle hummocky pitted surface (Fisher et al. 2002). This terrain displays a rough topography of pits, cracks, and some knobs (Thomas et al. 2000). Pits joined in roughly linear strings or depressions with preferential direction form lineations (Fisher et al. 2002).


From millimeter to tens of kilometers in width, from millimeter to hundreds of meters in depth. Pits studied by Fisher et al. (2002) in the northern ice cap of Mars are tens of meters wide and 1–2 m deep (Fisher et al. 2002).
