This is a maze that is cut out of a corn field. These mazes have become popular tourist attractions in North America; they are normally combined with other farm attractions of interest to families and day-trippers.
Example of Corn Maze:
In 2011, a family from Massachusetts was lost in a corn maze in Salem during a Halloween event. This cut out from a corn field resembles a labyrinth that can be fun to explore but can also be frightening if you don’t know your way out!
