Under the Canadian city of Montréal, a huge cave of 200 meters deep has been discovered by a few amateur geologists.

Discoverers Luc Le Blanc and Daniel Caron, who have been researching caves for years, react to Canadian media about the special discovery. 'It is beautiful,' says LeBlanc. 'The walls sometimes look like layers of fudge and chocolate. They are brown, dark brown and ocher yellow. '
