207 Boulder cluster

Geometry: point.

Definition

A distinct group of boulders so closely clustered together that they cannot be marked individually. The boulders in the cluster should be higher than 1.0 m.
A boulder cluster must be easily identifiable as a group of boulders.
To be able to show the distinction between neighbouring (maximum 30 m apart) boulder clusters with significant difference in boulder size, it is permitted to enlarge this symbol to 120% (edge length 0.96 mm) for some of the boulder clusters.
The symbol is orientated to north.
