In Memorium:

James H. Trexler, Jr., age 70, loving husband, father, sibling, and friend, passed away on May 15, 2017, after 55 cancer-free years followed by 15 valiant years living with multiple myeloma. Jim was a dedicated professor, mentor, and researcher. Born in Washington, D.C, he grew up in Oxon Hill, Maryland. Jim was a broadly inquisitive individual whose passion for the outdoors became part of his professional career. He was a geologist interested in what sedimentary rocks tell us about the Earth's history and the construction and erosion of mountains. He received his geologic training through the University of Maryland (B.S., 1974), University of Oklahoma (M.S., 1976), and, after several years at the U.S. Geological Survey with three field seasons in Alaska, the University of Washington (Ph.D., 1984). After teaching geology at Weber State University in Utah, Jim moved to Reno with wife Pat to start a 31-year career on the geology faculty at the University of Nevada, Reno. He thrived on the intellectual fun and challenge provided by studying geology with his students and colleagues throughout the western U.S., many of whom became his lifelong friends. He loved fieldwork, and spent several decades of summer field seasons on meticulous research with his students in the Basin and Range, Colorado Rockies and Colorado Plateau.

Jim was a professor at UNR, teaching generations of students from 1986 to 2017.
