Geoglyphs are large designs on the ground that are formed from earth or stone. These are typically classified as a type of land art. Geoglyphs are usually found in deserts in Peru and Kazakhstan, and now they can also be found in India!

It's not clear why the lines were made, though they are situated near several rock cairns, or stacks, and memorial stones, the latter carved with images of the Hindu deities Krishna and Ganesha. The lines may have some sort of religious or ceremonial meaning, discoverers and independent French researchers Carlo Oetheimer, and Yohann Oetheimer, wrote for the upcoming September issue of the journal Archaeological Research in Asia. The overall pattern is not visible from the ground, as there is no high point nearby and the terrain is flat. Only by scouting the region on Google Earth were the Oetheimers able to discover the geoglyphs.
