I just returned from a beautiful week in the desert, a perfect balm for the long gray winter. To complete the escape I left the computer home and am just going over images for the first time. The advantage is reliving the trip all over again but the disadvantage is not seeing the dust spots until now. One challenge shooting in the desert is finding organization in apparent chaos. A short hike on the Redstone Trail in Lake Mead Nat. Rec. Area was a case in point. The second two images were found in this small area along the trail.
