Cueva del Tunel   http://www.mexicancaves.org/maps/0440.pdf Jaumave Jaumave Survey by Greater Houston Grotto. February 1991. No date, no names. On "Canyon del Tunel".
From pp. 14-15 of AMCS Activities Newsletter no. 18, 1991: "Cavers from Houston, Texas explored caves along the Rio Guayalejo in late February 1985. Marcus Buck, Mike Connolly, John Fridye, Charles Fromen, Bill Rupley, Brian Smith and Harry Walker reached the large entrance visible on the north wall of the river canyon east of Jaumave. The steep, 750-meter climb above river level, culminated in a vertical, ten-meter pitch led by Marcus. They found the cave to be one large room, floored with dry guano dust. Dates written on the wall were Oct. 1, 1863 and 1960. Bottles placed under dripping formations provided meager water supplies for the group while they camped overnight in the cave. Local residents had no name for it, so they called it Gruta del Polvo. Descending back into the canyon, they looked at a wet-weather resurgence on the south side of the river. Large rocks are expelled by floodwaters, presumably from the Sierra de Guatemala which rises to the south. It would make a good dive prospect. Also visited was Cueva del Tunel, located in a side canyon southeast of ]aumave. Source: Charles Fromen"		 1991.
