MOUNT VERNON Washington City Lines Map: PRINTMOUNT VERNON, Washington. My hand drawn map centers on downtown Mount Vernon, extending north to Burlington and the intersection of I 5 and Highway 20, south to the Little Mountain Overlook. The eastern edge is occupied by the winding Skagit River an interesting organic, sinuous line on contrast to the city grids to the west. This is a PRINT of my original black ink line drawing.
