2011 Map of Diamond Swamp

About this map

The Donner und Blitzen River winds through the expansive Blitzen Valley, where a complex system of agricultural irrigation is evident through features like Skunk Farm Canal, Center Canal, and the East Grain Camp Canal. This 2011 survey of Harney County highlights a landscape shaped by both hydrology and volcanic activity, most notably at the Diamond Craters in the northeast and prominent elevations such as Jackass Mountain and Buena Vista Butte. Settlement in this high desert region is sparse, anchored by the Grain Camp and Anderson Ranch, which sit along transit routes like Center Patrol Rd and Diamond Ln. These landmarks reflect the long-standing ranching and water management traditions essential for life in this arid basin.
