Named for the city of Boulder, Colorado, about 48 km northwest of Denver. Settled in 1859 by miners and named for the large stones in the area, the University of Colorado was founded there in 1876, making Boulder a center for scientific and environmental research. The water supply for the city is unique, coming from the Arapahoe glacier high in the Rocky Mountains. The discoverer and his wife spent a year there at the JILA institution during 1967-1968.
