geoglyph
Let an agent explain geoglyphs and how they are made, relay major examples, dating and interpretation from archaeological sources with attribution, describe hill figures and hillside letters as regional forms, and distinguish geoglyphs from crop circles, earthworks in general and land art.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain geoglyphs and how they are made, relay major examples, dating and interpretation from archaeological sources with attribution, describe hill figures and hillside letters as regional forms, and distinguish geoglyphs from crop circles, earthworks in general and land art.
A large design or motif produced on the ground by arranging stones, removing surface material or shaping earth, from the Nazca Lines of Peru and the Steppe Geoglyphs of Kazakhstan to the hill figures of England such as the Uffington White Horse and other horse figures, and the hillside letters of the American West; geoglyphs are ancient and modern, visible often only from above, and are studied as rock art and protected as heritage.
What it is for: Not applicable; a landform and artwork category.
It can be explain construction; relay examples and interpretation; describe regional forms; distinguish related features.
Distinguishing features
Ground-scale design
Positive or negative technique
Ancient and modern
Aerial visibility
What it looks like
A large figure or line visible on a hillside or plain, often from the air.
Physical character
Nazca Lines: about 500 BCE to 500 CE period
Uffington White Horse: about 3000 years old note
Steppe Geoglyphs: up to about 8000 years note - estimates
largest hillside letter: about 200 m - estimates
How it is recognised
Large ground design
Nazca Lines, Steppe Geoglyphs, hill figures, horse hill figures, hillside letters
Crop circles are temporary; earthworks may be functional; land art is modern art

What the second pass must settle
- Should hill figure and hillside letter be separate primary entries?
- How should archaeological sources be linked?
- The registry entry has merged aliases naming regional forms and a specific site; should they be split off?
