The Cascadia Institute
The Cascadia Institute is run by David Mcloskey, a former Seattle University professor of sociology and geography, and who is one of the founding bioregionalists that helped give term this beautiful land of flowing waters 'Cascadia'. Aside from creating some of the must definitive, and stunning maps of the region, he practices and teaches 'Cascadian bioregionalism' which moves us away from pre-defined, existing and often arbitrary political boundaries, towards a watershed and community first approach, of getting grounded in our place, and the culture that it breathes, and every person taking a role and responsibility of what it means to be an inhabitant of this land.
