Explanation:

This is an Art piece by Robert Smithson.  It fits the category of Land Art or Earthworks inside Conceptual Art.

This art form is actually attributed to Robert Smithson.  It is ephemeral and has no utility function.  It is basically landscape art that uses materials, nature and landscapes interacting and merging together to create an aesthetic art form or to simply make a statement in the relationship we have as humans with our environment and surroundings.  It's a way to take art outside of the museums and expose the viewer to different situations, sensations and emotions.  It works like an installation in real life that fades or mutates over time.  

The art piece is exposed to the changes the outside contexts offers in terms of time, climate changes, pollution, etc so it is constantly changing or disappearing.  It is a way to reflect our mark on this earth and the intention to ask ourselves how we relate to these changes.

This particular piece, "Glue Pour", was created or should I say performed in 1969/70 in Vancouver, Canada.  It interpellates the viewer to the most irreverent and dramatic situation that we create as human beings in this world, Pollution.  It pretends to show how we react, and interact towards the environment.  It is a violent piece that faces us with the reality of our actions in this planet and what we do.  The action of pouring the glue disappeared as quickly as the glue spread, which leads to think how unaware we are of our pollution trace in this planet.
