Sinuous furrows a few kilometers wide and as much as several hundred kilometers long cover most of the quadrangle; in several places are broad regions many tens of kilometers wide that appear to be complex channel systems. None of these features can be correlated with markings seen from the Earth. </span><span data-ccp-props="{"201341983":0,"335559739":160,"335559740":259}"> </span></p><p><span data-contrast="auto">The major part of the quadrangle consists of moderately cratered material containing craters of different morphologic types. This region is typical of the most cratered region of Mars (Jones, 1974), have been previously mapped as cratered terrain, undivided (Carr and others, 1973), as moderately cratered terrain (McCauley and others, 1972), and as plateau plains (Wilhelms, 1974).</span></p>
