Charles "Chuck" Trantham (1936-2020)

"I was always interested in rocks and when growing up my great-uncle, Clyde Trantham, told me wonderful stories of lost mines, caves and treasures.
I graduated from Malta Bend High School in 1953 and enrolled that fall at Colorado State University in Fort Collins. My interest in rocks was further ignited by an elective course in mineralogy, which led to more geology courses, field trips, and mineral collecting with a fellow student, Walt Walker. Graduating in 1958 with a B.S. degree in geology, I went to the University of Oregon for graduate studies. While in Oregon, I first met AL McGuinness, who became a collecting partner of mine for thirty years"
