of the Dragon River, high over Infiernillo.We knew that waterfalls pouring in from theceiling must hold the key to progress tohigher entrances. At one cascade I was ableto climb an eroded column to gain access toan upper stream passage that I followed forabout 80 meters. Another waterfall requiredan overhung traverse to get into. After afew more cascades, I decided it would bebetter to return with a little climbinggear. Being the worse for wear, we electednot to survey, since we knew we would nowbe coming back to the beautiful DragonRiver another time. Five hours later wetrudged up to the fieldhouse to be greetedby a roaring fire and all our friends, whohad kindly stayed up late awaiting ourreturn. Great way to end a fine trip.PURIFlCACION 1987Catorce espeleologos del PEP pasaron diez dfas en el Campamento V dentrodel Sistema Purificacion en Tamaulipas, en marzo de 1987.

CUEVA DE LA LLORONAby Dale Patewith Peter and Terri SprouseThe obscure entrance to Cueva de laLlorona lies hidden in a brush-filled dolinasurrounded by large oaks near the crestof a hill in western Tamaulipas. The twometer-highentrance, situated at an elevationof 1820 meters, opens into a steeplydescending passage trending northwest towarda large valley. Near the northern endof this valley, three kilometers distantand 400 meters lower, lies the entrance toSotano de Las Calenturas, a six-kilometerlong, 120-meter deep cave system. And fourkilometers to the southeast is anothervalley that drains into Cueva de Tecolote,11 kilometers long and 220 meters deep.THE SURVEY BEGINSOn 20 November 1984, during a ProyectoEspeleologico Purificacion expedition toCueva de Tecolote, Gabino Torres showed thecavers the obscure entrance to Llorona,89
