there's lots of roots hanging down so
they coming through from the trees above
yeah these are coming through from the
OHA trees it's
amazing just like a Subway tunnel here
the walls perfectly round like took a
boring device and carved a tunnel
through here yeah pretty amazing isn't
it it is
phenomenal how long is this tunnel
system anyway 42 and 1 12
miles these caves in Hawaii are all over
the island and they're actually made by
lava the way they work is lava flowing
downhill cools the top it caps over and
suddenly it's flowing in pipik structure
and then the lava flows out and leaves
this Stone pipe so I'm actually in a
cave that was once filled with red hot
molten lava
