One comment on “The Flintstones

  1. Update from cycling forum:Flint is a specific form of chert found in chalk apparently. Part of the quartz family. It is very brittle, so particularly with the recent frosts some will have been cracked and the small shards are incredibly hard and sharp. And it seems as though it has nothing to do with grtiitng roads as “there is a lot of flint in East Anglia/ Essex (the old churches are all flint covered), and with the heavy rain after the snow, it’s washed out of the fields onto the roads.
