2020 Map of Flat Top Mountain

About this map

Flat Top Mtn serves as a central landmark in this high-desert region of southeastern Oregon, where the drainage patterns of Crooked Cr and Wildcat Cr reveal the essential water sources of the landscape. The existence of Pothole Springs and Crooked Creek Spring indicates the critical role of groundwater in supporting local land use in this arid portion of Malheur County. Navigation through the area is defined by a network of ranch and access roads, including N Fork Ryegrass Creek Rd and Crooked Creek Range Rd, which traverse the varied topography from Bone Canyon to the eastern plains. This 2020 topographic survey emphasizes the persistent importance of natural water features like Drought Cr and Bone Cr in defining movement and settlement boundaries across the high plateau.
