"Big Delta" lies at the intersection of the Delta River and the Tanana River. The city of Delta Junction sits on the Delta River at the intersection of the Richardson Highway and the famed Alaska Highway (actually, the end of the Alaska Highway). The city and Delta community lie within the fertile Tanana River valley. Three mountain ranges—the White Mountains to the north, the Granite Mountains to the southeast, and the Alaska Range to the southwest—and the Delta River to the west surround the city.
