N48 05.738 W123 33.287 Elwha Overlook

Near Olympic National Park, just off of highway 112, the National Park Service has set up a public viewing station facing what was formerly the Elwha Dam.  The platform is equipped with a high magnification spotting scope which one can use to peer into the various accelerated anthro-geologic  events happening there.  The series of images […]

River was: 34,131,100 points

The U.S. Geological Survey recently posted a LIDAR fly-through of what the Lower Elwha River looked like as of September 2011.  The composite of 97 on-the-ground LIDAR scans were made less than a week before the start of dismantling the Elwha and Glines Canyon Dams upstream.  The 34,131,100 georeferenced points of light will serve as […]

[A view of the shifting delta in what was Condit Dam’s Northwestern Lake.] It has been almost four months since Condit Dam was intentionally breached by blasting a tunnel through its concrete base.  As much has happened since then, here are some notes from the field. Amongst other events and trials, local media has remarked […]

Dam Erasure and Migrating Infrastructure
