I visited Nacimiento del Río Mante on a spring break caving trip to Mexico ten years ago. We were a group of dry cavers headed back from the Aquismon area. We camped by the spring and I fondly remember swimming on top at night and exploring the small amount of dry cave there. The stream of water coming up was ridiculously strong and very warm. It was a surreal feeling, looking up at the stars and moon, knowing that below your feet there was almost a thousand feet of water extending hundreds of feet below sea level. I remember thinking that Exley's depth record there felt like reaching the moon in terms of exploration.
