August 2013: Devil’s Staircase. On Aug. 22, 2013, Josh Laughlin and Cameron Derbyshire of Cascadia Wildlands led Rachael McDonald of KLCC Eugene and Stephen Lancaster on a trip to the Devil’s Staircase, the star attraction of a proposed wilderness area in the Oregon Coast Range. The video combines footage from the trip by Lancaster with an edited version of McDonald’s story for KLCC (Listen to the full story):

March 2015: The Porter Creek Project has new funding! The National Science Foundation, Geomorphology and Land-use Dynamics Program, awarded Stephen Lancaster a three-year grant to study Mountain Stream Sediment Transport at Porter Creek, Oregon (EAR-1452091).

Watch the instructional video featuring our newest pico-hydropower system at Porter Creek.


August 2018: Thanks to attendees of our RFID workshop! And let’s all thank The National Science Foundation, Geomorphology and Land-use Dynamics Program, for funding the workshop and project, Mountain Stream Sediment Transport (EAR-1452091). For those who attended, as well as those who didn’t, here’s an electronic version of the “Comprehensive Manual” featured in the workshop:
