Examples of archaeological sites where cropmarks have been observed are [[Balbridie]] and [[Fetteresso Castle|Fetteresso]] in Scotland.

In 2009, investigation of crop marks near [[Stonehenge]] revealed a variety of 6,000-year-old prehistoric subterranean structures.<ref name="natgeo">{{cite news|publisher=National Geographic|date=2009-06-15|url=http://news.nationalgeographic.com/news/2009/06/090615-stonehenge-tombs-crop-circles.html|archive-url=https://web.archive.org/web/20090620072414/http://news.nationalgeographic.com/news/2009/06/090615-stonehenge-tombs-crop-circles.html|url-status=dead|archive-date=June 20, 2009|title=Huge Pre-Stonehenge Complex Found via "Crop Circles"|author=James Owen}}</ref>

Another example is the rediscovery of the Roman city [[Altinum]], a precursor to the city of [[Venice]], from a combination of visible and near-infrared photos of the area taken during a drought in 2007,  which stressed the maize and soy crops. <ref> Ninfo A., Fontana A., Mozzi P., Ferrarese F. 2009.

The [[Mucking excavation|multi period site at Mucking]] was discovered as a result of aerial photographs showing cropmarks and soil marks. The earliest photographs to reveal the site were taken by the [[Luftwaffe]] in 1943.<ref name=Clark>Clark, A. 1993.

She said that some features do not produce crop marks and that some crop marks, when excavated, turn out not to be what they seem.<ref>{{cite journal|first=Margaret|last=Jones|title=Jottings from Mucking post-excavation|journal=Panorama|volume=25}}</ref>{{Full citation needed|date=February 2022}}
