Geologic map of the Darvel Quadrangle (MTM 20052), Maja Valles Region of Mars

The quadrangle is in the northern Maja Valles region on the west edge of the Chryse Planitia. This map is one in a sequence of three that also includes MTM 15057 and 20057. The sequence covers that part of the lower reaches of the Maja Valles that includes the transition from the higher Lunae Planum surface to the lower Chryse Planitia surface. The major interest in this quadrangle is the effects of catastrophic outflow and its associated morphologic modification of Chryse Planitia.
