Cylinder over Nelson, AZ

The report, as filed

My wife and I were driving to Nelson, Nevada, a ghost town where movies are sometimes made. We were traveling north on I-95 and the sun was behind us. We noticed a small cloud about 30 degrees elevation ahead of us and below it was a long grey smooth shape. Its length was about twice the diameter of the moon. It looked like it could have been a cylinder - or the rounded edge of a flat object. The bottom edge was less distinct than the top and faded abruptly to the blue of the sky, much the same as how the moon looks when viewed in the daytime sky. Apparently it was very high  to have that effect - and very large. Sketches sent by e-mail. We watched the object move left-to-right across our field of vision for about a minute. We couldn't stop to take a picture and we lost sight of it when the road turned. We were at: Lat: 35.7, Lon: -114.9 according to Google Earth. It did not have a cloud texture and was moving relative to the cloud, approximately east. The clouds were not perceptively moving. I suppose that the minimum altitude could be estimated based on knowledge of where the "fading" effect takes place for objects in the sky, but I don't know what that point is.
