A British father-of-two ventured deep into a crystal ice cave in one of the world's biggest glaciers for a rare glimpse of its ancient sculptures.<br />
Photograher Mark Andreas Jones, 42, braved sub-zero temperatures and battled across tricky terrain to take a look at the cave's hidden treasures.<br />
Only accessible in the winter months, the underground cavern in south east Iceland holds ice which formed more than 1,000 years ago.<br />
Mr Andreas Jones and friends spent two hours exploring the brilliant blue wonderland, hidden some 20metres below ground.<br />
