While on holiday in September 2021, I was reading older copies of the magazine BackTrack from the turn of the millennium, from, at that time, Atlantic Publishers. (More recent editions are published by Pendragon Publishing.)
Volume 14 No. 3, March 2000 included an article by Jeffrey Wells [1] about the Micklehurst Loop (p142ff).
