1987 Map of Donnybrook

About this map

Donnybrook and the surrounding high desert of the Oregon interior are captured in this mid-1980s survey. The landscape is defined by its drainage systems, notably Eagle Creek Valley and Little Trout Creek, which carve through the plateau. A small settlement at Post serves as a primary marker of human habitation in this isolated stretch where the boundary of Wasco and Jefferson counties meets. The map provides a detailed view of the terrain before later 20th-century shifts, showing a region where life was dictated by the availability of water and the rugged topography of central Oregon.
