Welcome to the new home of the compilation of long and deep caves of the world compiled by Bob Gulden for the Geology and Geography Section of the National Speleological Society. Bob worked tirelessly for decades to maintain these lists and I hope to keep his important legacy alive.<\/p>\n\n\n\n

Please be patient as I get the databases moved over and process the updates and corrections that have been coming in. These can be sent to Cavemonpaul at Hotmail.com. Each list will have the date it was updated at the top.<\/p>\n\n\n\n

Cave locations will not be given out, so do not ask. If you would like to donate to help keep this page going and to improve the features, click the button.<\/p>\n\n\n\n\n
