Wyoming scenic

Shot from Highway 80, west of Green River. This is a place I have passed and stopped by many times. I like it and was lucky to have a cooperative sky. Digital stitching with PTgui. I took overlapping images, butthere was some problem with the whole series, so this is only about 3 to 4 of the original series which was 7 shots. There was a lot more on the left and right, but Ineed to refine my learning in this stitching program to make the larger image.
