The states' land grant universities are both located here, less than eight miles (13 km) apart: Washington State University in Pullman and the University of Idaho in Moscow. Outside of these two cities, the two counties are predominantly rural and agricultural. The CSA is the center of the Palouse region, a former prairie characterized by its dune-like hills. The cities of Moscow and Pullman are roughly four miles apart, and are connected by Washington State Route 270, more commonly known as the Moscow-Pullman Highway.
