Regarding the thought and prospect of this system being much larger, maybe even to the point of there being a "passageway" to other nearby civilized
areas at that time... It's a very good question to ask.
I might not be an expert in this but just in my honest opinion, I doubt that we may ever be able to answer that.
Reason being: over time, gradually these lava tubes would become filled with sediment, debris and other obstructions. At a certain depth groundwater
seepage would be a problem and could lead to most tubes flooded and impassable. The ones that possibly extend out from the epicenter of the volcanic
flow would be impacted by the sea. Even if they were above sea level many years ago, they might be now. It would take experienced cave divers to
perform a mission like that, and it is not one for the faint of heart.
Which leads me to ask, does anyone know what the approximate sea level was during the apex of the culture? Could there be some high spots nearby that
could have been islands themselves?
Hrrmmm... just a thought.
