When the late Don Rhodewalt and his wife, Janice Samish, were looking to move from Oregon to Spokane in 1995, a friend who offered to help with house-hunting found them a beautiful Craftsman-style home on North Bowdish Road. It was not only the right size, it also was built out of what’s popularly known as river rock. Rhodewalt, a retired aerospace engineer, was fascinated by how his new house was built of rocks found on and around the property, carefully sorted – some are the size of watermelons, others not much bigger than golf balls – then stacked on top of each other and held together by grout.
