This image is a part of the Nazca lines, collected by the AVNIR aboard ADEOS on December 1, 1996. Known as the Nazca lines, many drawings, including geometric figures and biomorphic figures of a condor, a hummingbird and a monkey, were accidentally discovered in the early 20th century by a scientist flying over in an airplane. The Nazca lines are thought to have been created by the Nazca Indians who lived in the region between 300 BC and 800 AD. Since most of the biomorphic figures are only up to several tens of meters in length, they cannot be identified from satellite images. In the latter half of the 20th century, however, Landsat captured a huge arrow-like figure 50 kilometers long that points to South. The ADEOS/AVNIR also imaged a portion of this figure. These figures etched on the earth have led to some fanciful theories about their purposes, including the signals to interplanetary visitors or runways for alien spaceships. The Nazca lines were registered in 1994 as a World Cultural Heritage.
