The Middle Fork John Day River winds through the northern reaches of this Grant County landscape, set within the eastern boundaries of the Malheur National Forest. This 2017 survey documents a high-altitude terrain defined by steep drainage systems and prominent volcanic landmarks, most notably the Ritter Butte Summit and the distinctive Sugar Loaf Mtn. The map records a transition from these heights down into deep incisions like Flowers Gulch and Troutman Gulch. Aviation and transport are represented by Miranda's Skyranch Airport and a network of remote access points including Long Creek-Pass Creek Rd. The convergence of water bodies such as Granite Cr and Pass Cr illustrates the complex hydrology that has shaped these canyons over millennia, providing a detailed view of the region's topography and land use patterns.
