The Little Neath River Cave was discovered, explored and surveyed mainly by members of the University of Bristol Spelaeological Society between 1967 and 1987. Three reports on the cave were published, in 1967, 1971 and 1988. Each of these was accompanied by a survey of the cave. In 2008, the raw survey data was typed up, using Survex, and it is this data that appears in this archive. However, the dataset is incomplete. Much of the cave was resurveyed between 1967 and the publication of the second version of the survey in 1971. All this data is intact, as is later data, but some parts of the cave were not included in the resurvey project. When the 1971 drawing was completed, by A.G. Wilkins, who computerised the data and produced centre-line drawings using his own computer program running in Fortran, he found that much of the original data had already been lost and so he had to draw in those parts of the caves, including sumps 2-4, copying the 1967 drawing.
This is a perfect example of why this archive has been started.
Published Surveys and Models
The models are not as good as they might be as they lack the data that had been lost prior to 1971. Some of this has been replaced by digitizing sections of the published drawings.
