A trail marker has been placed at the Green Oaks Field Station in honor of Duane “Dewey” Moore,  a beloved professor of  geology, who passed on October 18, 2024.

Joining Knox in 1964 and teaching at the College until 1988, Moore helped shape a young geology department into one that produced a remarkable number of students who pursued Ph.D.s and profoundly impacted the broader scientific community. Over 24 years, including a decade as department chair, Moore’s interdisciplinary vision and commitment to fostering curiosity defined his legacy. The trail marker is located near the “Little Loop Trail” close to the lake. The stone is pegmatitic granite with muscovite, which weathers into illite, so named for Illinois, where it was first described in 1937.
