Mars digital-image mosaic merged with color of the MC-25 quadrangle, Thaumasia region of Mars. In the northern part, a prominent physiographic feature, Thaumasia plateau, includes a complex array of small- and large-scale faults and ridges and ancient volcanoes. Channel systems, upturned beds, and large troughs occur in places along the southern edge of the plateau. In the southern part, the lowlands that surround the plateau include heavily cratered highland terrain and relatively smooth, low plains. The east-central part is marked by a relatively young large impact crater, Lowell. Lowell is one of several large, relatively young impact events on Mars that followed the period of heavy bombardment. Latitude range -65 to -30 degrees, longitude range 60 to 120 degrees.
