What do you mean by a Geoglyph on the ground ?

In NGC or Discovery there would be episodes which would say about unknown mysterious presence in the world. Geoglyphs happen to be one of a kind. Thought of uncovering the real meaning of such figures


A geoglyph is a drawing on the ground, or a large motif, (generally greater than 4 metres) or design produced on the ground, either by arranging clasts (stones, stone fragments, gravel or earth) to create a positive geoglyph (stone arrangement/alignment, petroform, earth mound) or by removing patinated clasts to expose unpatinated ground (negative geoglyph).

Some of the well known Geoglyphs made by Nazca Civilization guys ages ago were :

Nazca Lines


Nazca Monkey


Nazca Desert Spider


Just imagine the discipline and the real-time thinking of these old civilizations. No airplanes or so at that time but still managed to carve and niche their humongous drwaings on the ground...Impressive
