After a presence of over a quarter century, the US Geological Survey moved from the Desert Laboratory on Tumamoc Hill to the University of Arizona campus. The Desert Laboratory is now being run by The Department of Ecology and Evolutionary Biology, and will have a new web site at http://www.tumamoc.org/.
