    Since I probably won't be able to post next week (thought I might try to sneak one in Sunday) I'm putting up some colorful images. Hope you like. Another place I'm unlikely ever to visit: Akpatok Island, Ungava Bay, Canada: From space: Akpatok Island lies in Ungava Bay in northern Quebec, Canada.

The Richat Structure in the Sahara Desert of Mauritania is easily visible from space because it is nearly 50 kilometers across. Once thought to be an impact crater, the Richat Structure's flat middle and lack of shock-altered rock indicates otherwise. The possibility that the Richat Structure was formed by a volcanic...
