in Cavertitz, SN·counted·98 all time
A stone marking a boundary, typically a small upright block placed at a property or territorial edge.
Counted, not streamed: Boundary Stone has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
