Fretted terrain
Fretted terrain is a type of surface feature common to certain areas of Mars and was discovered in Mariner 9 images. It lies between two different types of terrain. The surface of Mars can be divided into two parts : low, young, uncratered plains that cover most of the northern hemisphere, and high-standing, old, heavily cratered areas that cover the southern and a small part of the northern hemisphere. Between these two zones is a region called the Martian dichotomy and parts of it contain fretted terrain. This terrain contains a complicated mix of cliffs, mesas , buttes , and straight-walled and sinuous canyons . [1] It contains smooth, flat lowlands along with steep cliffs. The scarps or cliffs are usually 1 to 2 km high. Channels in the area have wide, flat floors and steep walls. [2] Fretted terrain shows up in northern Arabia , between latitudes 30°N and 50°N and longitudes 270°W and 360°W, and in Aeolis Mensae , between 10 N and 10 S latitude and 240 W and 210 W longitude. [3] [4] Two good examples of fretted terrain are Deuteronilus Mensae and Protonilus Mensae .
