Oregon Dunes Field Trip, Nov. 14, 2015

In mid-November, several members of the River Group went on a one-day field trip to the Oregon Dunes as part of the second field trip for Mark Fonstad’s seminar course on the Physical Geography of Oregon. The group hiked through the Dunes on the Tahkenitch Dunes Trail and Threemile Lake North Trail and made brief stops at Tahkenitch Lake and Clearwox Lake. River Group member Christina Appleby and fellow graduate student Dongmei Chen led the field trip and led a discussion of the formation, geomorphology, and changing ecology of the Dunes.
