A large (whatever that might mean) natural boulder or rock fragment that is not attached to the underlying terrain.
- For boulder fields and similar regions comprised entirely of large rock fragments, see natural=blockfield and natural=scree.
How to map
Mark the rock with a node and natural=stone (if stone is relatively big, you can put tag natural=stone to its outline).
To describe it further use the following additional tags:
- name=* to tag the name of the stone. I.e. "Doane Rock" in Eastham, Massachusetts.
- protected=yes - to tag cultural heritage management.
- website=* the url of a site with specific information to this rock.
- width=n - to tag that the stone has width of n meters
- height=m - to tag that the stone has height of m meters
Stone subtags in use
Some people have started to subtag stones with the tag stone_type=* (a total of 1485 in Sept 2019), with these values:
- conciliation_cross (1353)
- coat_of_arms (74)
- khachkar (23)
- ruhstein (19)
- grooves (6)
- place_of_worship (2)
- glacial_erratic (2)
Fewer have used the stone=* tag, but because others use the same stone-tag to refine material=stone, the situation is less clear. By Sept 2019, most values (on a total of only 122 stone=* objects) are describing the material of the stone (see also the much more used tag material=* for this).
