2017 Map of Flat Top Mountain

About this map

Flat Top Mtn dominates this high-desert landscape in Malheur County, where drainage systems like Bone Cr and Wildcat Cr carve through the arid terrain. The water sources here are critical landmarks, including Crooked Creek Spring and the aptly named Pothole Springs located south of the mountain. Human presence is marked by a sparse network of ranching or access roads, such as Tudor Rd and N Fork Ryegrass Creek Rd, which navigate the elevation changes between Bone Canyon and the headwaters of Crooked Cr. This survey illustrates the intricate natural hydrology of the region, showing how small seasonal streams like Drought Cr define the remote reaches of eastern Oregon.
