2020 Map of Fish Fin Rim

About this map

The Old Military Rd traces a historic path across this high desert landscape in Harney County, providing a glimpse into early transit routes through the eastern Oregon interior. The terrain is defined by dramatic escarpments, most notably the Fish Fin Rim and Big Fish Fin, which overlook the vast expanse of the Catlow Valley to the north. These geological features dominate the southwestern portion of the map, while the surrounding area is punctuated by essential water sources for cattle and wildlife, such as East Gulch Waterhole, Rimrock Waterhole, and Bench Top Waterhole.
