The geoglyphs take the shape of geometric shapes, mostly rings. The smaller ones are visible on the ground, but the larger ones can only be fully revealed from above. They also vary in size, from between 2-6 metres in diameter while others cover up to even 800 square metres. Many of the new geoglyphs have simple one-ring designs, while others are more complex, forming even at least six rings in an irregular patter. Moreover, some of the geoglyphs contain rock piles called cairns located beside or within them.

The geoglyphs were created by removing stones to expose the sandy soil below. They are said to have been created in the Late Intermediate Period dating to between 1050 – 1400 AD. It was a time when Quilcapampa flourished benefiting from the flow of people and goods through the town.
