Within Carlsbad Caverns itself, about thirty miles of tunnels have been explored.
Within the park is Lechuguilla Cave, which is much longer at 138 explored miles.
Jim White is credited as being one of the first explorers of Carlsbad Cavern. Others made claims that they too explored the famous cave, but little evidence exists to prove or disprove these claims. Jim White spent much of his life working in the cave, as a guano miner and later as a park guide, so his are the stories still told today. He is the iconic early cave explorer.
Luray Caverns is a privately owned entity, charging $23 per person for admission. By contrast, the entrance fee to Carlsbad Caverns -- a much larger cave -- is $6 per person, and entry is free six days a year.
The cost to visit Carlsbad Caverns National Park is $15 for adults aged 16 and older. Entry is free for children under 16. Additional fees may apply for guided tours or special programs.
I do not know too.
Being the longest cave explored (350 miles)
Yes
It takes about 45 mins to go from San Diego International Airport to Carlsbad, CA, traffic dependent.
About $250. But most of it is out of a fundraiser you have to do
None has been found yet, but it may still be found in the future - not much of space has been explored yet.
America was still pretty much not explored then, so would have been very beautiful and unspoilt
Prolly, as there are SO MUCH of warcraft that are not yet been explored, The Maelstrom for example.
That is unknown. Mokele Mbembe is a "cryptid". A cryptid is a animal in a scientific study [Bigfoot, Yeti, etc.] who's existence has not yet been proven. Its is very possible however that a creature like this could still exist in the jungle because much of it although has been explored with machines, it has not been manually explored.
