Removal of two dams on the Elwha River on Washington's Olympic Peninsula is allowing years of sediment and debris to make its way downstream and salmon to make their way upstream. Here's a stunning firsthand look at the river then and now.

"PORT ANGELES, Wash. - For more than 100 years, two dams controlled the Elwha river on the Olympic Peninsula. The Lower Elwha dam was built in 1910, 17 years later and 8 miles further upstream the Glines Canyon dam was built.   

When they were completed, the dams helped power the region's booming timber industry. In recent years however the relatively small power output and larger hydroelectric projects on the Columbia River made these two dams obsolete."
