I'm a Belize Tour Guide and do birdwatching tours back there reguarly.
In past years I've walked it with archeologist in very close inspection and I've be there several times lately.
I know exactly what its like. Their are some high spots raised above the water line and even some paleolithic rock outcroppings,
but still its a marsh wetland. The film is deceptive and your aware of that, any idiot can tell you've dredged up an access to the parts that aren't flooded and have the gall to show coconut trees and beach saying your selling Belize Jungle when what you have is mangrove littoral forest. Your a Con Man preying on the less fortunate people of Belize.
