Geologic mapping has provided observations that some features on Mars are morphologically similar to lunar Imbrium Sculpture materials. These grooved features occur in clustered sets of a dozen or more, are spaced 1 to 10 km apart, and are unlike other linear Martian features such as yardangs, faults, ancient valley networks, and mass-wasting features. We propose that they represent impact materials from an ancient basin. The orientations of these features were plotted as lines on a Schmidt net, and the density of the resulting intersections suggests a likely source area at approximately -26.0°, 125.0°, or roughly the center of Daedalia Planum. -from Authors
