There are many ways an artist can create a sense of movement in a piece of artwork, from blurring the back of a character to show movement, or showing the movement through air waves, arrows, and others. They can also make the character look like it is moving, and make the ground have more lines parallel to the movement, which will show movement.
hope this helps
The name of the artist and work is B. Robert Smithson, Spiral Jetty, 1970.
It represents an earthwork sculpture made of mud, salt crystals, and basalt rocks, and in the shape of a spiral. It is 460 meters long, and 4.6 meters wide, but also counterclockwise. It is located on the northeastern shore of the Great Salt Lake in Utah.
Brian found the flat stone somewhere between chapters 14 and 17.
