Chains and a photo from 1937.

customarily one chain wide.
Traditionally the Queen’s Chain is a strip of public-access land along coasts and waterways, of up to 20 metres wide. The strip of land was originally one chain (66 feet) wide.
The chain measurement also survives as the length of a cricket pitch, being the distance between the stumps.
A job as a chainman nowadays falls under the broader career category of surveying technicians.
Another treasure that Te Aroha Museum has is a photo of a group of people at the trig on the top of Te Aroha.
A triangulation station, also known as a triangulation pillar, trigonometrical station, trigonometrical point, trig station, trig beacon, or trig point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity.
By using known distances along the ground and angles it can be calculated how far a given point is from the top of the trig.
The physical component of New Zealand’s geodetic system is a network of control marks that serve as physical reference points.
A number of these marks are black and white trig beacons, seen on the tops of hills, or steel pins set into concrete in urban areas.
These marks are used by surveyors to determine the location of property boundaries in relation to the official geodetic datum.
The photo, taken back in 1937 according to museum records, shows a group of trampers by the trig at the top of Te Aroha.
Does anyone know who these people might be?
Any information would be greatly appreciated.
Te Aroha Museum’s opening hours after Labour weekend will be from 11am to 4pm daily.
