2023 Map of Sullivan Gulch

USGS Topo · Published 2023

About this map

The Umatilla National Forest and Whitman National Forest converge in this high-elevation landscape along the border of Union and Umatilla counties. The terrain is defined by complex drainage systems, including the namesake Sullivan Gulch and Cougar Canyon, where numerous named springs like Tamarack Spring and Doherty Spring provide critical water sources in the timbered backcountry. Modern recreation infrastructure is a prominent feature of this map, with extensive seasonal routes such as the 21 Road Snowmobile Trl and the Umapine Ohv Trl navigating the ridges. Notable topographic landmarks like Frog Heaven Meadow and Flat Rock Spring offer specific points of interest for those tracking historical land use or backcountry movement across the Blue Mountains.
