Scamander Vallis

A color image of Scamander Vallis on Mars; north toward top. The scene shows heavily cratered highlands dissected by the slightly sinuous gully of Scamander Vallis. The channel begins by dissecting a steep slope of an impact crater wall and abruptly ends about 180 km north of the crater.

This image is a composite of NASA's Viking medium-resolution images in black and white and low-resolution images in color. The image extends from latitude 13 degrees N. to 19 degrees N. and from longitude 330 degrees to 332 degrees; Mercator projection.
