I'm so glad we found your channel. We're in the process of buying a boat of our own as we speak and it's really inspiring to see other folks of our "era" living the dream. Love watching you guys.
Hi Karen. Thank you for watching. The sea and waves carved out an opening over time, horizontally, on the edge of the rock. Eventually it makes its way to a porous area that is vertical and eats away at it so the force of the wave pushes the water through a tunnel created over time which then channels upward. I think a lot of the rock is old, dead coral so it's very porous.
