Faux Rock
Here we have two rocks that are located at the convergence of a beach entry and a cantilevered coping.
A large biological feature shows three large faux rocks combined with real rock over a rubber liner.
This photo shows the starting pond waterfall on the feature above right, (#2) approximately one year after installation.

My brother's pool in Apple Valley shows the use of "satellite" rocks around the pool edge and raised  bond.  Changes in elevation are a good location for satellites as they make an excellent abutment for other hardscape. 

ie: "Satellites"

Please note that Satellite Faux Rocks can be absolutely any size.
