A handful of people with surveying gear are marking off this year's Mesilla Valley Maze in Las Cruces, New Mexico.
The nine-acre corn field will feature the silhouette of a man, a telescope and the Disney dog, Pluto.
It's meant as a tribute to the discovery of the dwarf planet.
Pluto was first spotted by a Las Cruces astronomer 80 years ago.
The corn should be 10-feet-tall when the maze opens September 25.
Organizers say 50,000 people are expected to walk through it.
