Cowiche Mountain and Sedge Ridge define the high country of Yakima County in this early 1970s survey. The landscape is a network of water management and seasonal transit, marked by the John Cox Ditch and numerous springs that feed into the forks of Cowiche Creek and Ahtanum Creek. The southern portion of the map is dominated by the Yakima Indian Reservation, with the Ahtanum Reservation Boundary cutting through the rugged terrain of the Ahtanum Ridge.
