207 Boulder cluster (ISSprOM 2019-2)

Geometry: point.


A distinct group of boulders so closely clustered together that they cannot be marked individually. A boulder cluster must be easily identifiable as a group of boulders. To be able to show the distinction between neighbouring (maximum 8 m apart), boulder clusters with significant difference in boulder size, it is permitted to enlarge this symbol by 20% (edge length 1.44 mm) for some of the boulder clusters. The symbol is orientated to north.


Footprint: 4.8 m x 4.0 m

Colour: black.
