A collage of glass bottles and ceramic vessels forms a colorful wall at the Lee Oriental Rock Garden.  These containers were once natural rock -- silica from which glass was produced.  It was then transformed by humans into objects of everyday life.
   Now they are returned to the realm of rock.  By combining them with concrete, a man-made rock formation has come into being!
   Rocks have traditionally been classified into three types: , , and .   But geologists are now starting to include a fourth type: anthropic -- rocks made by humans. 
   Anthropic rocks include structures big and small. This wall is very small compared to highways and dams, and it is a jewel.
   It's a mineral formation in its own right -- an organically formed mineral, and Mr. Lee's Garden is a study in anthropic rocks.
