The Department of Geosciences Spring 1999 . Volume 4, Number 2 Letter from the Chair Joaquin Ruiz Peter Coney's untimely death is the Department's sad news. In 1982 I read an ad in EOS describing a job opening at The University of Arizona.I had just finished my PhD dissertation on the origin of tin -rich rhyolites of the Sierra Madre Occidental in Mexico and had based many of my conclusions on Peter Coney's suspect terrane map of Mexico and his ideas of magmatism in the western US. I could barely wait to meet this scientist. His papers were imaginative and thought provoking. Of course, the papers reflected the man. After I got to know Peter, I was also struck by his humanity. Peter cared about people. He deeply cared for his students and was able to transmit to them his knowledge, his analysis and his calm. In fact, what made Peter such a remarkable individual Peter Coney in the northern Snake Range detachment . (photo by Peter DeCelles) was his genius combined with his humanity. Peter left us with many legacies -a legacy of great thinking of how the Earth works, a A Farewell to Peter Coneylegacy of great teaching, a legacy of how things are done in a collaborative spirit.

Aformidable education innovator within the department, Bob has driven much of the department's curriculum development and has also achieved NSF funding for educational efforts. Something I reflect on occasionally is the special culture and sense of community which our department possesses regarding our teaching functions. This is a department in which all faculty take their teaching seriously and the department staff (in my case primarily Norm Meader and Jo Ann Overs) provide major assistance which allows us to teach well. There are many excellent instructors in this department from whom I have learned much about teaching. Primary examples for me are Pete Kresan, Randy Richardson, George Gehrels, Michelle Hall - Wallace, and Julie Libarkin. It is particularly noteworthy that faculty and students who put major effort into their teaching are recognized within our

This year's GeoDaze Symposium gathered students, faculty, alumni, industry folk and friends together on April 8 -9 for the 27th consecutive year of undergraduate and graduate presentations in the earth sciences. Drawing an audience from as far away as Alaska, two poster and three oral sessions kept the extended family of the Department of Geosciences abreast of student earth science research being conducted at the UA. Whereas the general success of GeoDaze is dependent on a number of individuals and institutions, the outstanding quality of student presentations truly separates GeoDaze from its counterpart symposia. The Evaluations Committee, headed by Joy Gillick, pointed out that the calibre of student research presentations underscored the wholesale success of UA geoscience students in a diverse array of disciplines. The Evaluations Committee made significant strides towards improving the feedback and evaluation process this year. By making evaluation forms available to all, organizers worked towards keeping the collaborative and cooperative Top Row (L -R): GeoDaze Award winners Mandi Lyon, Dena Smith and Carmala Garzioni.
