Caves/Lava Tubes

[HADave]

Tony, do you recall if they allowed large lighting? I'd love to explore and learn more of these unique environments but suffer from night blindness (nasty glaucoma) The thurston lava tube was a bit of a struggle and we even tried stepping into the darkness beyond the exit stairs,where the tube continues on, with our small 2 cell mag lights but it wasn't enough, even 10 feet in was scary when you can't see and the floor is so irregular. If not for the light of the exit disorientation would have made for an easy panic situation. non-the-less it was exciting. Thanks for sharing your story
