More Clouds!

We lost two nights of our three night run to cloouds/fog. The type of cloud is an "orographic" cloud, one that forms over a mountain. Moist air is forced up over the mountain, it cools, and loses the ability to hold moisture, so a cloud forms. This picture from John Weirich at the University of Arizona's Lunar and Planetary Labs shows an extreme example of such a cloud.
