About this map

Irish Lake sits at the center of this high desert landscape, surrounded by a network of seasonal water sources and grazing lands. The eastern edge of the map is defined by the Blitzen Valley, where the Donner und Blitzen River and the Warm Springs Canal provide a more consistent water supply than the interior basins. The terrain is marked by significant volcanic features and depressions, most notably Hole in the Ground and Hoghouse Canyon.

Evidence of historical range management and early settlement persists through labels like John Cabin Spring, Dead Cow Spring, and Company Trough. These features, along with numerous man-made basins such as Monument Reservoir and Bed Ground Reservoir, suggest a landscape shaped by the needs of livestock in an arid environment. Transportation through this remote corner of Harney County relies on a few primary routes, including Jack Mountain Rd and Foster Flat-Harney Lake Rd.
