We In the March 18th issue of are proud of this achievement as it reflects our commitment to excellence in teaching U.S. News and World Report, the and research in the geosciences. The Faculty Awards and Honors section listed in this Department of Geosciences has newsletter is a testament to our continuing achievements. tied at 9th place in the top -ranked This newsletter has a few new sections that we hope you'll enjoy. The first is a geology departments around the section on Alumni News. We heard from many of you and we're passing on the good country. The specialty programs news to our readers. We are particularly proud of the achievements of our alumni and our hope is that this section will grow exponentially with time as more of you write in of tectonics and structure ranked with your own news. 4th. These rankings are the result The second item is a report from the chair of our Geosciences Advisory Board, of the U.S. News survey of Steve May (PhD '85). I'm very happy that Steve has taken on the responsibility of department chairs and heads of chairing this Board. I think Steve's hard work, and that of his fellow board members, graduate studies and is a direct will be rewarded by a sense of accomplishment in seeing our department progress measurement of the strength and even further. reputation of our graduate Inside this newsletter you'll also read about Vance Haynes and PhD student program Kathleen Nicoll in the Sahara, Andy Cohen and his environmental efforts with Lake Tanganyika, the very successful field trips by Mark Barton in Mexico, George Gehrels, Pete DeCelles and Jay Quade in Nepal, and Suzanne Baldwin and Paul Fitzgerald in Antarctica. As Bill Dickinson once said, a good geology department must always T have a few of its faculty in the air at any one time. By that measure it seems we are doing well! Here in Tucson, faculty and students were busy with the Tucson Gem and Mineral Show and in developing methodologies to teach geophysics in both large and INSIDE small educational environments. We continue with the tradition of profiling some of our recently retired faculty and this time it's John Guilbert's turn. We also have sad Unroofing the Himalayas: news and we pay tribute to three of our colleagues who have recently passed away - UA Geoscientists in Nepal ........4 Eloise Grijalva, Bart Nagy and Ted Smiley.
