This was a early evening hike along the Lake Michigan shoreline taking pictures from atop a parabolic dune... when viewing the pictures the next morning (8-16-13) I noticed a short streak traveling in a W/SW direction. Magnification of the image is not indicative of jet contrail or star trail as there is nothing in view in the proceeding or following images.
