Recent images from a series of NASA's and ESA's Mars spacecraft missions have provided greater details of the Martian landscape. At present, the surface of Mars is extremely cold and dry; a similar environment on Earth is the so-called “polar desert”. Landforms of the inland mountains of Antarctica are generally regarded as the best analogous forms to those on Mars. Large-scale fluvial landforms on Mars, which suggest that liquid water once flowed on the surface, have been recognized. Furthermore, topographic forms similar to glacial or periglacial origins on Earth have been suggested to occur on Mars. However, the criteria for the formation of rock glaciers and debris-covered glaciers on Earth are not directly applicable to those on Mars. The debris covers of the glaciers on Mars are possibly formed in a manner similar to the formation of the sublimation till cover found in Antarctica.
