World's Largest Human-Made Art by Jim Denevan

Jim Denevan is a Santa Cruz, CA-based artist who makes freehand temporary drawings in sand using only a stick and a rake. Working up to seven hours and walking long distances to work on his drawings, Denevan completed what has been identified as the largest human-made art on earth.

Located in Nevada, this drawing is three miles across, and it reportedly took 100 of miles of walking to draw the pattern.

Denevan, who is a chef by profession, creates simple geometric figures in the dry sand as a kind of temporary sculpture. Many of his drawings are done by the water and they are then, sadly, washed away by the rising tides.
