If you've come across a massive Nordic troll in the wild lately, chances are you're not hallucinating—you've just discovered one of Danish artist and environmentalist Thomas Dambo's gigantic, hand-built, recycled sculptures. His Pacific Northwest-based project, Northwest Troll: Way of the Bird King, has seen six humongous Nordic trolls land in scenic spots across the region, including Bainbridge Island, Issaquah, Vashon Island, West Seattle, and Portland. The final one will be unveiled at the National Nordic Museum on September 18, and they’ll be installed across the region for at least three years. The trolls, which are "characters in an environmental story penned by the artist," serve to illustrate critical lessons of environmental stewardship. Spy the other troll spots on Dambo's online map, too.
