Surveys

Eastern Massif caving expeditions

The following surveys are available from the expedition. Surveys from older expeditions are in the process of being redrawn with modern software and will be made available once complete.

Surveys by clubs, not currently involved in the Tresviso Caves Project, are also included in either their original form or as revised drawings by the expedition. Permission to reproduce has been sought, where possible, but a number of the original clubs no longer exist. Please contact the expedition with any concerns or more surveys to contribute!

                              The following surveys relate to caves not in the immediate area of exploration but maybe of interest in a wider context, especially as some are resurgences for areas ‘close’ to Tresviso.
