2020 Map of Diamond Swamp

About this map

The Donner und Blitzen River winds through the Blitzen Valley, defining a landscape where volcanic geology meets intensive water management. This high-desert region is marked by the unique topography of Diamond Craters and the prominent Jackass Mtn, which overlook a complex network of man-made waterways including the Skunk Farm Canal and S Diamond Canal. These irrigation features, along with Diamond Drain and the Center Canal, indicate a history of modifying the naturally arid basin to support local agriculture and livestock. Within the vast Diamond Swamp, the map documents essential water sources like Oliver Spring, Unit Nine Pond, and Hay Willow Spring. Isolated landmarks such as Buena Vista Butte serve as navigational anchors along the sparse road network of Center Patrol Rd and Lava Beds Rd.
