2020 Map of Sullivan Gulch

About this map

Whitman National Forest and Umatilla National Forest converge in this high-elevation landscape on the border of Umatilla and Union counties. The terrain is defined by a dense network of seasonal and year-round springs, such as Half Moon Spring, Blarney Spring, and Doherty Spring, which feed into the drainages of Camas Cr and Campbell Cr. This modern survey illustrates how the forest is managed for seasonal recreation, featuring specialized routes like the 21 Road Snowmobile and the Umapine OHV trail. Notable landmarks like Frog Heaven Meadow and the deep Cougar Canyon break the timbered slopes, while the eponymous Sullivan Gulch sits in the eastern portion of the quadrangle. The map captures the specialized infrastructure of the Blue Mountains, where old forest tracks and named water sources like Tin Trough Spring remain vital markers for navigation and land management.
