- 2017 May 25, The White Horse, Nr Alton Barnes, Wiltshire. Puzzle-like crop circle  phenomenon appears to be a combination of two previous pieces which were documented earlier in the year.
- 2017 May 22nd, Cerne Abbas Giant, Nr Minterne Magna, Dorset. The meaning is debated among crop circle researchers. The complexity and lack of evidence of human activity has left an impression of being paranormal to researchers.
- 2017 May 21st, Oxleaze Copse, Nr Stitchcombe, Wiltshire. The formation appears to depict a solar eclipse comparative to a 2004 design that also depicted a celestial event. The appearance of the 2017 crop circle predates this summer's solar eclipse by three months, just as the 2004 formation did. This pattern suggests that the crop circle makers see the solar eclipse as a significant event.
