• One or more well-defined peaks--odd in number if more than two. All sides slope down and outward. 
• Main peak is offset to right or left of center. 
• Height and depth are 1/4 to 1/2 stone's overall length. 
• Basic outline is that of an asymmetric triangle. 
• Distant Mountain, has smooth subtle contours. 
• Near View Mountain, shows rugged surface detail. 

Island Stones--SHIMAGATA ISHI

• Many features in common with Mountain Stones, though some have lower profiles, steeper sides. 
• White quartz "breakers" at base are a special plus. 
• I personally prefer Island Stones that also show some indication of a cove or landing site

• A level plain parallel to the base leads to a peak at one end, approximately 1/4 the stone's overall length. 
• Plateau joins the peak along an open-face diagonal as viewed from the front. 
• Some Dohas, instead of level plains, feature low-lying foothills rising toward a distant peak. 

• Two or more ( more is better) flat parallel levels, including the top as one of these levels. 
• Levels vary in size and in height of vertical rise. 
• Top level has approximately 1/4 of the total area covered. 

• The waterfall is indicated by quartz or other light colored inclusions in a dark background material. 
• Waterfall originates at or near the top, preferably between two peaks of unequal height. 
• Width of waterfall increases as it descends. 
• Waterfall cannot run over and down the back side. 
• Falls are often featured in other Suiseki styles.
