2013 Map of Iowa Flats

About this map

The Rattlesnake Hills Research Natural Area occupies a significant portion of this landscape, encompassing the prominent peaks of Rattlesnake Mtn and the surrounding Rattlesnake Hills. This area in Benton County shows a transition from high desert ridges down toward the Iowa Flats and the Cold Creek Valley. Water sources are few in this arid environment, making features like Sam White Spring and the drainage of Cold Cr critical landmarks for understanding the local topography and early land use. The presence of Goose Egg Hill further north and the linear path of Wa-240 cutting through the terrain highlight the intersection of natural volcanic geology and modern infrastructure in the vicinity of the Hanford area.
