Focus on El Capitan

This image, taken by the microscopic imager on the Mars Exploration Rover Opportunity, shows a geological region of the rock outcrop at Meridiani Planum, Mars dubbed "El Capitan." Light from the top is illuminating the region. Several images, each showing a different part of this region in good focus, were merged to produce this view. The area in this image, taken on Sol 28 of the Opportunity mission, is 1.3 centimeters (half an inch) across.

An odd geographical formation for such an environment, i.e. high winds lasting for long periods of time. Especially when viewed with its neiboring region, i.e. A rocky, ridged, rough area with this cemetrical fromation, very odd in my opinion. Wonder what set of circumstances could create such a formation

Looks like an Oolite to me---what is the matrix that it has weathered out of.Reminds me of carbonitic Oolitic ooze---no ? can't be that.The matrix appears to be packed with them.Lateritic crust? raymo41.
