The significance of the Audio Overview here is it states
a provenance
for the land art's presence.

It is built of records generated in the earliest years as consideration came into play of the meaning The Great Knot's form as a knot would bring to the world it would be a permanent part of.

Art always occupies two environments: one actual and one virtual. The Great Knot land art sculpture is a place, and knots are things. Both are actual. But the graphics and writings about the significance of these places and things are virtual.

History is virtual without a place; a foundation. The role The Great Knot site plays in this is what the work here is about... visitable forms of environments that understand the same virtual thing a chronology of historical provenance has as it spans hundreds of millions of years that the land art acts as a surrogate for, using the knot topology as a symbol of an eternal progression.

So there is a cryptological significance in the site specific character... about time and timelessness.

The Great Knot is about the ebb and flow of the tide water environment of the Hudson Valley that trades the depths of the Atlantic Ocean for what its foundation of the continental plateau at the Catskill escarpment has sculpted. The runoff of this complex intermingling of energies courses right through The Great Knot.

Man's changes in the environment of the Hudson Valley has marked the land with initiative and resolve. Not a stone is turned without uncovering forms of both the present and primordial past. This quarried-over region has incised its record into the earth's very bedrock.

The mists of time have rained down awareness upon every atom of this environment to bring it a limitless quantity of creative material to pay homage to the concept of limitlessness.
