AND GEOTRAILS
The Gerny Anticline
You will find yourself at the highest point of a flattened area. From Rue de Ninove onwards, you will have
passed by a number of disused quarries (not always easy to spot, as they are fenced off). Were you to continue northwards, you would come to the Boverie quarry, mentioned above. Geologically speaking, you would still be treading Calestienne limestone all the way from the On quarry to the Boverie. Along most of its length, the Calestienne is a strip less than a mile wide. Here, however, it is at its widest at 4 km, as a result of a geological anticline: this is the Gerny plateau, or Gerny anticline, which stretches
eastwards from Rochefort as far as Hargimont. This slightly rolling limestone plateau was covered by windborne silt loam deposits ideal for crop-growing.
