Cenote Diver, Mexico
Photograph by Tian Tian, National Geographic Your Shot
A diver explores Mexico's Aktun Ha cenote—also known as Car Wash—in this photo selected for a Travelogue story on National Geographic Your Shot.
Contributor Tian Tian says the dive was his first at the site, a popular destination for cave and cavern diving. In summer, he says, "there is an algae layer at the surface, which traps much of the sunlight and creates a mysterious green atmosphere."
