The Department of Geosciences is saddened by the recent passing of long-time professor John Guilbert. John was an extremely well-known, well-respected and important part of our program and legacy, and many faculty and alumni remember him and his influences very fondly. After his retirement, John continued to be engaged and generous with UA Geosciences, sponsoring the economic geology talk prize each year at GeoDaze. Among his many accomplishments, John advised scores of economic geology students and taught classes and geosciences field camp. He also established a legacy of international trips in Canada, South America, and Australia, finding sponsorship for all the students that attended.
