This image from NASA's 2001 Mars Odyssey spacecraft of Daedalia Planum shows the termination or end of a single flow. In this case it is the end of the brighter/rougher flow on the right side of the image.

Arcuate Fratures

This image from NASA's 2001 Mars Odyssey spacecraft shows evidence of tectonic stresses that deform and fracture rocks and planetary surfaces. Right angles seen here are a good indication that the feature was formed by tectonic stresses.

This unusual surface texture is found on the northwest part of Olympus Mons as seen by NASA's Mars Odyssey. The origin of this texture is unknown, but speculations include glacial or volatile rich materials as part of the cause of such textures.
