The tourist attraction, which has been dubbed the "Great Blue Hole," is a collapsed cave that measures approximately 984 feet across and 410 feet deep. NASA scientist Glyn Collinson once described it as the "deepest, deep blue hole imaginable." In November 2018, researchers with Vancouver-based Aquatica Submarines sent a three-person submarine to the site to explore the bottom of the Great Blue Hole for the first time. They even completed a two-hour live broadcast from the deep blue waters that was featured on The Discovery Channel. As far as billionaire business magnate and Virgin founder Richard Branson – who joined the expedition – is concerned, there is no mythical monster hiding in the depths of the Blue Hole.
