The other day I stumbled across an old reference tree. I was actually looking for another survey mark to set my GPS on. When I turned around I saw a tree with a blaze and a broad arrow carved in it. I was pleased to find it as there aren't many old reference trees remaining. They have either been chopped down, the ants have eaten them or the tree has grown over the mark making them difficult to find. Ok, I did give it a coat of paint. We use yellow quite abit in Australia.
What colour do you use for survey marks?
Have you found any interesting survey marks lately? We'd really love to know about it.
Write a short desciption about the mark, your name, your location and send us a photo.
Survey marks vary all over the world.
Why not share the differences with your fellow Global Surveyors.
