ABOUT US
Our goal is to foster an understanding of Earth Science concepts by offering five-eight (5-8) illustrated lectures during the academic year and one or two summer field trips. We focus mainly, but not exclusively, on local and regional geologic features and issues (see yearly list under events). Membership and events are FREE and open to the public, although we gratefully accept donations to defray our expenses. QGS is an earth-science activity of the Jefferson Land Trust, which is located in Port Townsend, WA. We are in our 10th year here on the Quimper Peninsula.
