| Overground there are ring forts and burial monuments, round towers and high crosses and always the flat limestone slabs with cracks, or grikes. |
| And the top itself is magic, a flow of fissured limestone pavement with very deep grikes, so the beer cans are out of sight. |
| Bryophyte and other vegetation mats close over deep grikes but will not support human weight. |
| The solution of vertical joint sets into grikes characteristically fragments the pavement surface into blocks known as clints. |
| There is something about limestone – its glints and grikes, the little flowers that grow in the crevices – that satisfies the child's eye: the geometric lines are an invitation to play. |
| Rarer species to be found in the grikes include baneberry and downy currant. |
