AbstractA party of surveyors en route for Fort Augustus at the south-western end of Loch Ness on the Caledonian Canal in Scotland would not cause many eye brows to be raised. But when that same party requires two dozen table tennis balls one might wonder if they intended to enter for the table tennis championships or maybe whether they had found some intriguing way to capture the Loch Ness monster. The answer however is much less romantic but infinitely more practical than tangling with the kelpies of the dark waters of the Highlands; the table tennis balls were required for targets in a geodetic triangulation scheme. The triangulation was part of a study being conducted by geologists into crustal movements in the Great Glen fault which runs in a north-east, south-west direction across the Highlands of Scotland.
