This archives contains cave surveys from Hong Meigui and other expeditions to China. We wish to include as many surveys as possible, with the aims of providing a large database for scientific use, clarifying what exploration has been done in China and by whom, minimizing data loss between expeditions, and reducing duplication of effort. If you'd like to contribute to the archive, please contact Erin Lynch at

Surveys marked CCP are from China Caves Project expeditions and are copyright China Caves Project.

Recent Hong Meigui surveys have been drafted using Adobe Illustrator. See here for more information about the symbols used.
