Geologic Setting

The site is on the southeast margin of Acidalia Planitia and on the northern edge of the highland-lowland boundary. Nearby materials include the Vastitas Borealis grooved member, hummocky undivided material, Plateau Sequence cratered unit, and Arcadia Formation flows with lobate margins.

Scientific Rationale

Contact between northern plains and southern cratered highlands.

Objectives

Sample northern plains, fractured terrain, base of cratered highland remnants (may measure time sequence of debris aprons), volcanic constructs, and pseudocraters.

Potential Problems

Sampling area consists of smooth plains. Debris from erosional remnants may cause some problems. Fractured terrain may be difficult to traverse, but need only be sampled at edges. Erosional remnants may cause some problems when landing, but should be avoidable. Sampling operations should be simple.

Trafficability

mostly 1; maybe some 5.

Estimated Traverse Distance

100 km.
