About

Glines Canyon Dam is now a symbol of ecological rebirth, showcasing one of the most ambitious dam removal and river restoration projects in history. This site, nestled within Washington's breathtaking Olympic National Park, offers visitors a unique opportunity to witness nature reclaiming its course. What was once a barrier on the Elwha River is now a vibrant, free-flowing waterway, demonstrating the remarkable resilience of ecosystems.

The primary "exhibits" at Glines Canyon are the interpretive panels located at the accessible Glines Canyon Spillway Overlook, which narrate the dam's history, its removal, and the ongoing recovery of the Elwha River ecosystem. From this vantage point, you can gaze upon the stunning Glines Canyon, observe the Elwha River's blue-green waters carving new paths through former lakebeds, and see remnants of the immense concrete structure. The real spectacle, however, is the returning wildlife, particularly the various species of Pacific salmon and steelhead trout, which are once again migrating upstream to spawn, a sight rarely seen for over a century.

Visiting Glines Canyon is more than just a scenic outing; it's an immersive educational experience that highlights successful conservation. It offers a profound connection to the natural world and a powerful message of hope for environmental recovery. The transformation of this landscape makes it a memorable destination for anyone interested in nature, history, and the incredible power of restoration. Don't forget to bring the Snappit nature identification app along to scan local species.
