Surveying: This technique has been an important part of the Hidden Heritage Project.

  • Walkover surveys have been used to look for and record new features in the landscape between Arrochar and Tarbet.
  • Geophysical surveys have been used to detect traces of manmade features that leave no signs on the surface
  • Plane table surveying has been used to produce accurate plans of particular structures, like the old sheep fank
  • Digital survey using highly accurate electronic equipment (electronic distance measuring device, EDM) has been used to plot the positions of all the old gravestones in Ballyhennan graveyard.

Walkover: S3 pupils from Hermitage Academy helped with the walkover survey at Creag an’t Searraich, which revealed the remains of two, or possibly three building-like structures, as well as an area of rig and furrow, a possible corn-drying kiln (or maybe just a hole left by some tree roots!), and lots of banks and ditches. Children from Arrochar and Luss Primary Schools will help to excavate this site in May.

Building Survey: Brian Wilkinson visited both the primary schools to show pupils from P4-7 how to do a basic survey of a building using simple equipment, and how to produce a scale drawing of their ‘discovery’. Brian also visited Lomond School and introduced them to the use of a plane table to draw accurate scale plans.

Zip-less Geophysics: Pupils from Arrochar Primary came to watch Cathy McIver from Northlight Heritage and some volunteers carrying out a geophysical survey of their school playing field. They helped to peg out the guidelines for the survey, and learnt that you can’t wear anything metal – not even zips! – when you’re using some of the geophysics equipment!

Graveyard Recording: S1 pupils from Hermitage Academy and S2 pupils from Lomond School helped to record some of the old gravestones in Ballyhennan graveyard. These date from the mid-1700s to the recent day, with one fascinating exception that may be as early as the late 1400s.
