Curious Dimples

This image from the Mars Exploration Rover Opportunity's navigation camera was taken on the rover's 71st sol on the red planet. On the previous sol, the rover drove beside a sinuous trough in the plains of Meridiani Planum to get a closer look at its curious dimples. The rover then approached the pictured trough area referred to as "Anatolia." From a distance, the rocks here resemble those in the "Eagle Crater" outcrop. These rocks will be imaged in greater detail with the rover's cameras.
