Rational: Remnant buttes give access in a
very limited space to many layers.
The objective will not be to drive to all of
them, but to target the closest to the actual
landing site, and possibly some other(s) on
the way to other targets.
Morphology & mineralogy: Small remnant
buttes are present throughout the area (the
ellipse is not completely flat), but the largest
and highest one are all found east of the
ellipse, just before the flank of Mawrth Vallis.
We are not considering here remnant buttes
of the dark cap, which are numerous at the
site. All these buttes are located in large
Fe/Mg-smectite bearing outcrops, but the
top of the highest buttes may reach the Alphyllosilicate level.
MSL tasks: At large scale, study the layering
of the two sub-units, the transition from one
to the other. At small scale, study the
layering, the grain structure, the mineralogy
and chemistry of the rocks and the variations
from one to the other sub-unit and within
each sub-unit.
