Erosion rate and previous extent of interior layered deposits on Mars revealed by obstructed landslides [PDF]

open access: yes, 2014
We describe interior layered deposits on Mars that have obstructed landslides before undergoing retreat by as much as 2 km. These landslides differ from typical Martian examples in that their toe height increases by as much as 500 m in a distinctive ...
