About this map

Coulee City Airport anchors the northwest corner of this agricultural landscape in Grant County, marking the transition from aviation to the vast grid of the Columbia Basin. The terrain is defined by a series of distinct coulées and depressions, most notably Garland Lake, which sits within a complex system of contour-defined draws and ridges. A rigid township and range system dictates the movement through the area, with routes like Road L NE and Road 36 NE following section lines across the high desert plateau. The survey illustrates how late 20th and early 21st-century infrastructure relies on these established cardinal boundaries, with local connectors such as N-Ne RD and Road 31 NE providing access to the interior rangeland and scattered water features typical of this part of Eastern Washington.
