Another set of interesting Christmas period explorations in the 4 Valleys System - specifically at the end of Shrimp Bone Inlet and Sandstone Passage in Trident, Cueva Hoyuca. The big find for Simon Cornhill and Diane Arthurs was 'el Gordo' a large chamber off Armageddon. The video is 25 minutes long with 'el Gordo' starting at 16:25.
