The concept is to include 3 elements, rock, eucalyptus trunks and water, in a single environment which, when combined with light and turned upside down, will give visual access to the watertable.The rock becomes the upper element. Dead trunks stand upside down, their roots spreading out below the rock. The water is lower element.
The installation will be very site-specific. The size, scale, materials used, and other pertinent factors will be determined by negotiation, practicality and the site of the installation.
