We were airborne and did a three quarter of a full circle turn banking to the south and then straightened out north wards. As we flattened out, we could see West Caicos. Even thru the airplane window, the picture came out well. The island is mostly empty but I understand it is being built out as a high end resort place.
The lake inside (Lake Catherine) has the same sky blue water. And the reason is that it is connected to the ocean thru underground inlets. (Even the tides come in and out! )
