Geoglyph
A geoglyph is a large-scale man-made feature on the ground. Usually longer than 4 metres, it is made by placing rocks, stones, live trees, gravel, or earth.
A positive geoglyph is formed by the arrangement and alignment of materials on the ground, while a negative geoglyph is formed by removing material to expose bare ground.
