In 1996, Spokane Valley resident Don Rhodewalt began cataloging homes built of river rock (or cobblestones) in Spokane Valley. Rhodewalt lived in a river rock home at 1105 N. Bowdish Rd. and he was fascinated by the building style, which he'd never seen before.
His criteria were simple: the house had to be located in Spokane Valley or nearby communities and a significant part of it had to be built out of river rock; a river rock foundation or rock chimney was not enough.
He cataloged the homes on this map - but died before he could finish the project.
