The Cave

This cave system runs for many miles underground and is explorable from November to June. It is prone to seasonal flooding during the monsoon months: June to October. Apparently there are warning signs discouraging visits during the rainy season.

The moment the group are found

This is the transcript of the conversation between Rick Stanton, John Volanthen and the trapped children.

John: How many of you [are there]?

Children: Thirteen

John: Thirteen? Brilliant!

John: There's two of us.... we had to dive.

John: We're coming, it's ok. Many people are coming. We are the first.

Children ask what day it is

John: Monday. One week and Monday. You have been here 10 days. You are very strong, very strong.

Surfer's ear is the common name for an exostosis or abnormal bone growth within the ear canal. Irritation from cold wind and water exposure causes the bone surrounding the ear canal to develop lumps of new bony growth which constrict the ear canal. The condition is not limited to surfing and can occur in any activity with cold, wet, windy conditions such as windsurfing, kayaking, sailing, jet skiing, kitesurfing and diving.
