2018 Map of Keystone North
USGS Topo · Published 2018About this map
Keystone serves as the primary hub on the southern edge of this agricultural landscape in Benton County. The terrain is defined by a dense grid of township and range lines, including t84n r12w and t84n r11w, which organize the farm-to-market road network that still dominates the area. The drainage of Prairie Cr meanders across the lower sections of the map, providing a natural break in the otherwise structured sections of the high plains.
