Any of you learned Cornish folk know what is the symbol on the 1/2 Mill Chart, to the north-west of Camborne, approx - N 50° 15’ W 005° 20’?
It looks like a racetrack with 3 x ‘shark fins’ inside it. It is not identified in the legend or in the notes. Much debate has gone on but we cannot figure it out.
I have discounted the proposed theory that it is a holding pattern for Great White Sharks as everyone knows Great White Sharks don’t go around in threes!!
