Black mountain

 This appears to be two mountains on either side of the highway heading towards Cooktown. As the name suggests it is black with no vegetation about 15 mms south of Cooktown. There was an earth cache there so on our way to a pub (yes, I know! We were going to a pub) we dropped in.

I don't usually like earth caches as they make me feel dumb but this one appeared easy to do. All answers could be found in the information boards. Plus a photo to determine that we had been there. 

260 million years ago, lava pushed through a crack in the earth so the rocks are volcanic and originally light grey in colour but lichen has grown on them making them appear black, isn't that neat.
