Hidden Earth 2025
Matienzo Caves 2025 - the 65th Year
45 minute Lecture|Juan Corrin
Abstract
There may be some reminiscing in our 65th year of exploration - but the talk will concentrate on finds made since the previous Hidden Earth, including 'El Gordo' a large chamber in Cueva Hoyuca. That space helped to take the length of the Four Valleys System to over 78km.
