The rocks and the quarries
Every named rock, crag, reef and quarry the open map records inside the city, 31 cliffs and crags, 8 rocks, 1 reef and 5 quarries, from the Port Hills' volcanic tors to the pits that built the city’s kerbs. The crag names are the climbing community’s own; the dual names are the map’s.
What the record says
- 1,003 stones sit unnamed beside these: roughly 22 without a name for each the map calls by one.
- The climbers did the naming, 16 of the 31 cliffs carry “crag”, “wall” or “climbing” in the name.
- Just one reef makes the roll, Kamautaurua Island.
- Of the 5 quarries only Old Halswell Quarry carries the map’s historic tag.
Where they sit
OpenStreetMap’s own pins, a formation’s pin on its ground, a quarry’s near its middle. The high places keep their own roll at /summit.

Questions, answered briefly
31 named cliffs and crags, 8 rocks, 1 reef and 5 quarries on the open map: plus 1,003 more drawn without a name, the Port Hills' volcanic tors and the pits that built the city.
The climbing community’s own, Castle Rock, The Tors, the workout walls of the Port Hills, recorded on the map alongside the older Māori and English names. Each page lists every name the map knows.
The quarries are where the stone left the hills, Halswell’s basalt built the city’s kerbs and walls. They are mapped as landuse=quarry; the register’s listings for them live at /history.
OpenStreetMap, every named cliff, rock, reef and quarry inside the city boundary (ODbL). A pin is the mapper’s position, not a surveyed mark.
