This internationally-known, contemporary residence is characterized by extensive moss rock walls. A dry streambed was built into an existing natural drainage pathway to simulate a steep mountain cascade. Boulders create falls in the steeper portions for snowmelt or rainwater. Granite scree and river washed stones line the streambed to visually connect clusters of boulders. Shrubs, small pines and perennials accent the falls and break up the home’s 300-foot long horizontal rock wall while Aspen trees provide a strong vertical element.
