see below for the author's description
"Each square of this Quilt Map of Oregon represents 12 miles square. The map is loosely based on land use maps from the Atlas of Oregon (q.v.). Quilting represents county boundaries. Most major cities, mountains, and lakes are shown, and are accurately placed within four or five miles. Those familiar with the state should be able to pick out the Ochoco, Strawberry, Blue, and Wallowa Mountains, as well as familiar features like the Willamette Valley, Mt. Hood, Crater Lake (and Wizard Island!), and the lower Columbia River. " -Michael5000
