Keystone serves as the primary hub at the southern edge of this landscape, situated in the fertile agricultural plains of Benton County. The map documents a highly structured rural environment defined by a rigid grid of local thoroughfares such as 15th Ave and 66th St, reflecting the persistent logic of the Public Land Survey System. These roads connect isolated homesteads and smaller clusters like Rogersville to the north, which sits along the upper reaches of local drainage systems.
