Definition

An area which is covered with so many scattered blocks of stone that they cannot be marked individually is represented with randomly placed and orientated solid triangles. The runnability is reduced and is indicated by the density of the triangles. A minimum of two triangles shall be used. To be able to show obvious height differences within a boulder field, it is permitted to enlarge some of the triangles to 120%.
