Recent ice ages on Mars
Evidence is shown that dusty, water-ice-rich mantling deposits on Mars formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago, a key pacemaker of ice ages on the Earth. Expand
Northern lowlands of Mars: Evidence for widespread volcanic flooding and tectonic deformation in the Hesperian Period
[1] Recent Mars Orbiter Laser Altimeter (MOLA) data have provided a new picture of the Martian northern lowland basin topography and surface roughness. In order to assess detailed topographicExpand
Possible ancient oceans on Mars: evidence from Mars Orbiter Laser Altimeter data.
High-resolution altimetric data define the detailed topography of the northern lowlands of Mars, and a range of data is consistent with the hypothesis that a lowland-encircling geologic contactExpand
Mars: Nature and evolution of young latitude-dependent water-ice-rich mantle
[1] High-resolution altimetry and imaging have revealed the presence of a meters-thick sedimentary layer at middle to high northern and southern latitudes presently covering at least 23% of theExpand
Kilometer‐scale roughness of Mars: Results from MOLA data analysis
The Mars Orbiter Laser Altimeter (MOLA) data are used to characterize the kilometer-scale surface roughness of Mars. The median absolute value of the differential slope at a given baseline isExpand
Martian gullies in the southern mid-latitudes of Mars: Evidence for climate-controlled formation of young fluvial features based upon local and global topography
A new survey of Mars Orbiter Camera (MOC) narrow-angle images of gullies in the 30°–45° S latitude band includes their distribution, morphology, local topographic setting, orientation, elevation, andExpand
Tropical to mid-latitude snow and ice accumulation, flow and glaciation on Mars
Images from the Mars Express HRSC (High-Resolution Stereo Camera) of debris aprons at the base of massifs in eastern Hellas reveal numerous concentrically ridged lobate and pitted features andExpand
Extensive valley glacier deposits in the northern mid-latitudes of Mars: Evidence for Late Amazonian obliquity-driven climate change
Understanding spin orbital parameter-driven climate change on Mars prior to ~ 20 Ma ago requires geological evidence because numerical solutions for that period are chaotic and non-unique. We showExpand
Recent high‐latitude icy mantle in the northern plains of Mars: Characteristics and ages of emplacement
[1] Martian high-latitude zones are covered with a smooth, layered ice-rich mantle containing characteristic polygonal patterns. The mantle is especially uniform and homogeneous in the northernExpand
Fate of outflow channel effluents in the northern lowlands of Mars: The Vastitas Borealis Formation as a sublimation residue from frozen ponded bodies of water
[1] We analyze the fate of the Hesperian-aged outflow channel effluents emplaced into the northern lowlands of Mars. We have modeled the evolution of these effluents under the assumption that theyExpand
