1979 Map of Roseburg

The valley floors are dotted with small agricultural and timber communities like Lookingglass, Coles Valley, and Dillard. To the east, the terrain rises into the Umpqua National Forest, while the western edge reaches toward the Coast Range and the headwaters of the Millicoma River. Infrastructure follows the river corridors, with the Southern Pacific railroad and Pacific Highway serving as the primary north-south arteries through Roseburg and Myrtle Creek.
