The OS co-ordinates show up a link on Bing Maps satellite mapping to "Ivanhoe Haulage Grab, Digger & Crusher Hire" placed right where the "Crop Circle" is on the moor. Their actual company address is Unit s11, Mamhilad Park Industrial Estate, Pontypool NP4 0HZ. How the link was placed precisely on the crop circle site in the middle of nowhere on the North York Moors is as much of a mystery as the DUP-funded Pro-Brexit Metro Newspaper colour supplement of last year. And may hint at similar dark forces at work related to free advertising "For a range of machinery available to hire for your groundwork projects call Ivanhoe Haulage Grab, Digger & Crusher Hire in Abergavenny"
Looks like a weeedkiller and strimmer job to me. With the strimmings hauled away on some form of transport via the access road at Stot Sike on Ravensgill Rigg.
