      COLUMBIA RIVER CRUISE



      Holly Ryan, Andy Stevenson, and Jim Vaughn are back from a successful but

      HOT--+100d F!) 5-day reconnaissance cruise to the Columbia River collecting

      high resolution geopulse data in search of recent upper crustal faulting, as

      part of the Cascadia earthquake hazards project.



      Al Niem from Oregon State University joined us for two days.



      Data were collected aboard the Cathlamet Bay, a 26-foot Army Corps of

      Engineering boat that allowed data acquisition in only a few meters of water.



      The logistics of mounting all of the equipment on the boat was somewhat of a

      headache, but the expertise of the boat driver, Terry Vance of the Corps, more

      than made up for the lack of space, and contributed immensely to the success

      of the cruise.



      Although we were not able to image much more than about 10 to 20 m below the

      river bottom, we did observe evidence suggestive of recent faulting at several

      sites.



      These included the northern and southern bounding faults of Portland Basin,

      near Portland International Airport, near the now defunct Trojan nuclear power

      plant, and along northwest trending faults in the lower Columbia River near

      Astoria.



      We hope to be able to go back at some time in the future using a larger source

      to be able to confirm our results.
