1996 Ortho Quad satellite image of the Chena-Tanana area.
Notes:
A 1996 Ortho Quad satellite image shows that the long narrow tree-covered island to the southwest of the old townsite of Chena is eroding away. Also note that the gravel pit first indicated in the 1963 topographic map persisted as a body of clear water, even though the U.S. Army Corps of Engineer's (USACE) most downstream groin had been built at its northern edge.
