Fellow cavers, We are presently in the process of reinstating the Quintana Roo Speleological Survey's position as a project of the National Speleological Society. In the meantime, we have been updating the data files of the known caves in Quintana Roo. After all available data was compared, we are pleased to announce that the longest, surveyed underwater cave in the world is now Ox Bel Ha at 43.88 miles/70.65 kilometers. According to Bob Gulden's long cave list, this makes Ox Bel Ha the 18th longest cave in the world. This is an incredible achievement considering that the initial exploratory dives by Sam Meacham and Bil Phillips began in January of 1998 (dry cavers should consider the difficulty of surveying imposed by the underwater environment). The latest data for the longest caves in Quintana Roo are as follows: Cave System Length Depth Reported by Date 1. Ox Bel Ha 70 650 m -33 m Sam Meacham 1/00 2. Nohoch Nah Chich 60 985m* -72m Dan Lins 1/00 3. Sistema Dos Ojos 55 322m* -101m Jim Coke 1/00 *Some of the lengths indicated here are shorter than previously published, this is due to survey and data entry errors that previously extended the length of the caves. These data errors have been identified and resolved to generate the lengths presented. Happy caving and cartographically yours, The Directors of the Quintana Roo Speleological Survey, Hazel Barton Jim Coke Dan Lins Gary Walten We would like to thank Larry Fish for his help in producing a conversion program that has allowed much of the QR survey data to be converted to a usable form in Compass.
