Hidden Earth 2026: Confirmed Lectures, Films and Workshops
'We wouldn't have an event if we didn't have lots of exciting lectures so we encourage all cavers to submit a talk, film or workshop. You can submit your abstract online any time throughout the year - even if you haven't been on that expedition yet!''
Im visiting Mt. St. Helens and the surrounding area soon, and I heard some lava tubes around there are worth look. Definitely visiting ape cave, but its hard to find the details on other tubes. Has anyone here been, and where would you recommend?
