1953 Map of Elephant Mountain

About this map

Moxee Valley irrigation and military infrastructure dominate this mid-century landscape east of Yakima. The northern half of the sheet is occupied by the high, ridged terrain of the Yakima Firing Center Military Reservation, where Yakima Ridge gives way to deep erosions like Washout Gulch. In the lower agricultural basin, the complex plumbing of the high desert is visible through the winding course of the Roza Canal, supported by numerous Siphons and a dedicated Pumping Sta.
