Most people driving across southern Wyoming take I-80. But if you have a little extra time take Hwy 130 west out of Laramie and cross the Medicine Bow Mountains. You go through Centennial at the eastern edge of the mountains, cross the mountains (which are part of the Medicine Bow National Forest), go through Saratoga on the western edge of the mountains, and rejoin I-80 just east of Rawlins. The scenery is great. Snow closes the road during winter, and you can see plenty of snow right through summer.
This picture is of Mirror Lake at a National Forest Picnic Area. The fog gave a mystic quality to the scene. But you couldn’t see the mountains. I took the photo in July of 2006; note the snowbank on the left edge of the photo.
