Nothing but rubble is left of the dams blocking the Elwha River. The last bit of concrete structure was demolished on Tuesday.
The Peninsula Daily News reports the Elwha River is free to travel its own path for the first time in a century.
The final 30-foot section of the Glines Canyon Dam was destroyed by an explosion at 4:12 p.m. Tuesday. Crews with Barnard Construction Inc. of Bozeman, Mont., detonated charges at the site.
An Olympic National Park spokeswoman says the debris from this week's blasts will be hauled away over the next few weeks.
The Glines Canyon Dam on the Elwha River was completed in 1927. The older Elwha Dam, which was completed downriver in 1913, was destroyed earlier this year.
