Broken Sword - Smoking Mirror

I am playing George on Zombie Island. Have the net with stone inside on top of needle. My problem is I can't seem to find the place where I can use the surveying tripod. Keep getting lost in the swamp. Can anyone help me from being lost?
Getting very dizzy.
Thanks for any help

its on a cliff looking out into the bay at the other end of the island. just north of that needle i think. its been so long. you can see the 3 holes on the cliff top to put the tripod
