La Grande and the surrounding Grande Ronde Valley are defined by the meeting of the Union Pacific railroad and the winding Grande Ronde River. This 1963 survey shows the city during a period of institutional growth, anchored by Eastern Oregon College and the Grande Ronde Hospital. The urban grid transitions quickly into the fertile lowlands of Island City, where a complex network of sloughs, including Gekeler Slough and Pierce Slough, dominates the drainage pattern.
