To see a map and links to each area, try the index by area page. These are most useful if you are following a complex cave description described over several pages, or if you are just browsing for new insights. Many pages have illustrations, usually small images to speed loading. Most of these are linked to pages with a full size image and some explanation - just click on the image to see this. There will be links back to the description, to more pages of pictures, and often to other relevant pages.
Every page has a table of links at the bottom like the one below .
These are useful if you are reading the full page, and then want to move on to a related topic. Some pages act as index pages, such as a cave exploration history linked to the write-ups of each trip, or a glossary of passage names linked to cave description pages. Each line or list item has a link to the relevant point in another page. If you see a year of exploration highlighted as a link, it will take you to an index of information about the expedition of that year. Logbook pages often have sets of links to next and previous trips in the same cave at the end of each write up, so you can follow logically the exploration of a given area or passage, even when the trips were written up in the logbook out of sequence, and mixed up with trips to other places.
