|The Christmas party at Frozen Deep|
The group – called The Tuesday Diggers – decided to hold their annual festive party in a massive cavern they discovered in September.
A gruelling hour-long descent led the five revellers to the Frozen Deep, a 98ft-high, 200ft-long chamber in the Mendip Hills, near Cheddar, Somerset.
The pals lugged Christmas decorations, party hats, food, mulled wine and even a Christmas tree through 150ft of narrow rock passageways to liven up the cave.
Caver Martin Grass said: ‘It was definitely the most interesting Christmas party I have ever been to."
