Geologic Setting

Site lies in an area containing Hesperian terrain (Hvm) with probable fluvial material, Amazonian terrain (Aa5); volcanic terrain with local lava flows overlying alluvial fans, and Noachian terrain (Npld); cratered upland.

Scientific Rationale

To be determined.

Objectives

Sample of in situ materials and talus materials from Npld (cratered upland); sample and return of fresh crater ejecta materials; sample of probable fluvial sediments (Hvm) and volcanic (basalts?) materials (Aa5); calibrate size/frequency crater curve.

Potential Problems

To be determined.

Trafficability

Moderate on Hesperian terrain (Hvm). Poor on volcanic plain (Aa6).

Estimated Traverse Distance

50 - 200 km.
