We have a very long Canyon more than 1 Km, I believe it could be the connection between the two continents and loads of tec divers go and dive that site, so I would like to document it also to start monitoring the change happens in the reef. Our goal is to create a 2D map and 3D map. Its a very long canyon starts from 30 to 60 meters. It has some parts of it overhead and some others are open. It is a 8-10 minute swim from the shore in the Northern cost of Dahab.
