North Cascades National Park

North Cascades National Park in Seattle has created an environmental learning center that's completely green. Eighty percent of the construction was made with recycled goods; there's a rooftop rainwater harvest, green lighting and solar energy. The best part is the center is open to the public. Designed to inform visitors about green building and other topics — and as a general meeting place — this is a must-see if you're in the Seattle area.
