When the Sun goes down... (1) - Sol 813

A spectacular field of Martian sand ripples separates NASA's KMER Spirit from the slopes of Husband Hill. It has been 200 Soles, since Spirit started a descent from the top of the peak to its current position on Low Ridge. Looking back to the North, on Sol 813 (such as April 17, 2006), Spirit acquired this blue-filter (436-nanometer) view with the right Pancam while the Sun was low in the sky late in the afternoon.
Because of the low-angle lighting (sunlight is coming from the left), images like this provide superb views of subtle textures in the topography both near and far.
Husband Hill, where the Rover was perched late last Summer, rises prominently just left of center in this view (frames 3, 4, 5 and 6).
A 150-meter wide (500 foot) field of curving sand ripples named "El Dorado" (frames 4, 5 and 6) lies at the base of Husband Hill.
