HiRISE: Along a scarp
Along a scarp. All along this section of scarp of a canyon in Kasei Valles, there appears to be a lobe-shaped margin of something (lava? mud? flood sediments?) that flowed into this trough, coated the floor and subsequently drained. What’s … Continue reading

HiRISE: Textures in Deuteronilus Mensae
This enhanced color image shows the surface of a lobate debris apron in the Deuteronilus Mensae region of Mars, on the boundary between the Northern plains and Southern lowlands. These lobe-shaped formations commonly emanate from mesas in this region and … Continue reading

Debris aprons and valley fill hold ancient ice several hundred million years old
Along the edge of the crustal dichotomy, where the southern highlands step down onto the northern plains, lies a landscape of mesas, buttes, and valleys. Valleys appear choked with linear streams of debris, and on the flanks of many mesas … Continue reading

Latitude controlled Amazonian ice flows
Signs of underground ice deposited in the Amazonian period (the most recent in Martian history) are common in many places on Mars. Evidence includes tropical mountain glacier deposits, lobate debris aprons, lineated valley fill, concentric crater fill, and pedestal craters. … Continue reading
