Inversion of relief on Mars

Evidence of volcanic and glacial activity in Chryse and Acidalia Planitiae, Mars

“…Their crested tops, very high tributary junction angles, and branching patterns are most consistent with eskers (Kargel and Strom, 1992). Locally, the thin ridges seem to overlap both highs and lows in the ridge-and-furrow surface, thus defying local slopes; this is considered diagnostic of eskers (Shreve, 1985;Kargel and Strom, 1992;Pain et al, 2007).…”

River meandering on Earth and Mars: A comparative study of Aeolis Dorsa meanders, Mars and possible terrestrial analogs of the Usuktuk River, AK, and the Quinn River, NV

“…Several Martian valley systems have undergone extensive aeolian deflation of fine-grained deposits, leaving channels in inverted relief (Williams and Edgett, 2005;Pain et al, 2007;Williams, 2007;Mangold et al, 2008;Newsom et al, 2010). Most of these are fragmentary or exhibit low sinuosity, but an extensive set of inverted sinuous channels is exposed in the Aeolis Dorsa region, centered at about 5°S and 150°E (Burr et al, 2009(Burr et al, , 2010Williams et al, 2009Williams et al, , 2013 (Fig.…”
