This painting perfectly contrasts and compares man-made structures with the colossal figures of a canyon/rock formation. They are seemingly similar, but the fact that the natural form is pasted on top of the cityscape shows, perhaps, its lesser value or impermanence in comparison to the building. Of course the rock formation has been around much longer than the building, but its importance to humanity is subsiding (I think) and that is where the idea of impermanence/unimportance comes from. The lines connecting points on the canvas show an interconnectedness of nature and city. It looks like the lines indicate that they are dependent on one another. Would the man-made structure exist without the nature made structure? Or furthermore, would we exist? Probably not.
