2017 Map of Hartline NW

About this map

Upper Grand Coulee defines the northwest corner of this landscape, where the waters of Banks Lake meet the steep-walled edges of the basalt plateau. The terrain is characterized by the dramatic transition from the coulee floor up to the high, rolling fields of the Columbia Basin. Coulee Blvd follows the shoreline, while a precise grid of rural roads, including Rd 42 Ne and 39-Ne Rd, stretches across the high ground to service the region's agricultural parcels. The natural drainage of Chase Draw cuts through the central portion of the map, illustrating how local topography dictates the movement of water and the placement of transportation routes in this part of Grant County.
