Stretching 100 miles along Interstate 90 from the small town of Thorp in Central Washington to the Seattle waterfront, the Mountains to Sound Greenway is a "Wilderness on the Metro," a place to walk or bike or picnic, to quickly get outside and explore the beauty of the Northwest. The mission of the Greenway Trust is to protect and enhance scenic beauty, recreational opportunities, wildlife habitat, historic communities and healthy economies in a multi-purpose Greenway along Interstate 90 from the shores of Puget Sound over the Cascade Mountains to the Kittitas Valley foothills in Washington State. Help make this human and natural heritage visible and accessible to all people. In 1990 a concerned group of citizens marched from Snoqualmie Pass to the Seattle waterfront to publicize the need to save some of the nearby forests and open spaces just outside of the growing city. From that group of activists, the nonprofit Mountains to Sound Greenway Trust was formed and began building a Board of Directors that is now a coalition of 68 people. The Board includes major land owners and managers along Interstate 90, foresters, business representatives, recreation groups, environmentalists, community activists, elected leaders and government agencies.
