This year in early March I had the opportunity to visit Mexico to check out the Tulum ruins as well as dive in the many freshwater sinkholes called cenotes. Not only were the ruins breathtaking but so were the cenotes and their life giving crystal clear water. The Mayan words "Ts'onot" or "Xenote" generally mean "well" or "waterwell" and refer to any source of fresh groundwater. Hundreds of feet deep, most cenotes are unexplored in their entirety and it is believed that most (if not all) are connected, making the area near Tulum possibly the largest freshwater underground river system on Earth. This area is a hot spot of speleological research which involves highly technical deep-water and cave diving expertise, making it the go-to destination of it's kind. Nikon D3200 / GoPro3+
