EXPONENTIAL POT update

VSA has been running one trip per year into this great cave since about 2009. The cave is highly protected due to its excellent state of preservation, so the trips are rare, carefully managed, and always have a genuine working objective. So far the main objective has been to check and improve the mapping of the system, with the result being the publication last year of The Exponential Atlas. Photo-documentation of the cave is also undertaken, with the results supplied to PV. The main objective for the next trip will be to enter the more remote southern area and check the surveying and mapping. This part of the cave is the least documented, and mapping improvement is almost certain to result. Some surveying might be undertaken.
