Pointed thatched huts, with their roofs sculpted by desert winds, cast long shadows in the warm, saturated afternoon light. The Tuareg village, located in the Sahara Desert of Libya, looks abandoned, or at least temporarily vacated, perhaps by its nomadic inhabitants moving on. The foreground is pocked with footprints, but how long ago were they made? Windblown sand fills the entrance of the hut closest to us, at right. Above it all, lines of long strata clouds in a brilliant blue sky seem to outline the desert’s contours.
