2020 Map of Monumental Rock

About this map

Monumental Rock rises as a prominent landmark on the south bank of the Snake River, anchoring a landscape where the river carves through high plateau country along the Franklin Co and Walla Walla Co line. The settlement of Ruxby and the nearby locale of Magallon sit nestled within the drainage breaks south of Lake Herbert G. West. This 2020 survey illustrates the modern land use patterns of the region, where the steep topography of Skookum Canyon and Cow Bar Canyon dictates the path of local corridors like Magallon Rd and Casey Rd. To the south, Walker Canyon cuts deep into the terrain, highlighting the geological transition from the river valley to the uplands. The presence of Three Springs Bar suggests the historical importance of river access points in this corner of Washington, where geography and hydrology have long shaped human habitation and transport.
