2014 Map of Mosquito Flat

About this map

The Malhuer National Forest encompasses much of this high-desert plateau in Harney County, where the landscape is defined by a series of springs and deep canyons. The Silvies River winds through the northern sections, supported by numerous water sources including Bob Bennett Spring and Rimrock Spring. The terrain is marked by significant geological features such as Mahogany Ridge and Gravel Ridge, which rise above the surrounding flats. To the south, Heifer Canyon and Varien Canyon demonstrate the erosive power of seasonal drainages like Poison Cr and Dry Cr. This area is intersected by the John Day-Burns Hwy, which provides a primary transit corridor alongside a network of Forest Service roads. Local history and ranching roots are reflected in names like Peabody Spring and Hixon Brandon Spring, indicating the critical importance of reliable water in this arid environment.
