The Pena Colorada is an enormous fossil resurgence, hypothesized to be the overflow resurgence to Sistema Huautla. Preparations are now underway for a return to the Cueva de la Pena Colorada in Spring of 2018.

The last expedition to push the Pena Colorada
was in 1984, oranized by Bill Stone and the USDCT. The current end of exploration is in sump 7, which starts at the bottom of a 55 metres deep vertical shaft and quickly goes to a depth of 50 metres. In 1984 the team stopped exploration when they hit the logistical limits of open-circuit dive gear; Stone described sump 7 the "ultimate speleological obstacle". It was after this expedition that Stone started to develop the famous CIS-Lunar rebreather, to overcome the logistical limits of open-circuit gear. http://www.usdct.org/pena_colorada84.php

Over the last couple of years the next generation of cave divers has resurrected exploration in Sistema Huautla. Read more on our webpage:
In particular recent expeditions have focused on the active Huautla Resurgence. Video from the 2017 Expedition:
Now, 34 years later, cavers will return to the lead at the limit of exploration of the Pena Colorada, which is a wide open 10 meter diameter tunnel heading northward towards Sistema Huautla. 2018 will be the first time divers return to push this lead equipped with closed circuit rebreathers, and other advancements allowing for long and deep penetrations.

A cave diving expedition of this magnitude is not cheap. Expedition members pay for expenses out of pocket (not to mention expensive personal dive gear). This campaign is our humble attempt at raising funds to soften this financial burden. Funds raised here will go towards expedition food, and travel expenses to transport a very large quantity of gear to a very remote place.
