The number of surveyed caves on the island exceeds 100. Most of them are small, but the longest and best known. Ana Te Pahu, is 910 m long. Detailed exploration and survey in a couple of areas on the island resulted in discovering of several new caves. We estimate that the total number of caves on the island exceeds 300. A complex survey of these objects would provide a good guidance for archeologists since in most of them we found archeological sites with artifacts.
In December 2004, during the preparation of another expedition, we spend six days on the island. Beside numberous meetings with local administration we surveyed another 8 new caves. The longest of them is over 200 m long and has more potential. According to local advice we did not named the caves, they will be named in compliance with the knowledge and tradition of the oldest citizens of the island. I hope that this project, though not very spectacular but requiring lots of work, will find more enthusiasts as we plan another expedition for November 2005. This hopefully will give us more insight into the underground world of RAPA NUI.
