The tunnel was constructed from indigenous limestone blocks.
Have a look:

Dr. Paul Guptill, was, by odd coincidence, the state’s reknowned “resident” scientist who visited schools specifically for the purpose of educating kids about science.
He was our “teacher”, in name, for that particular day.
My “less than scientific observation” was eye witness testimony to what I and everyone else saw that day.
*shrug*
Pick that apart how ever you may.
I saw them.
End of story.
So your hypothesis, based upon one visual observation 37 years ago, is that all stalactites grow at the same accelerated rate so therefore the sciences of archeology, geology, and chemistry must be wrong? Before I take that giant leap of faith can you tell me what the specific limestone type is that the blocks were comprised of, what the water source is, and what the mortar mix was that the water encountered along its path through the construction? Can you also tell me what the xbar, r, and standard deviation of the ambient temperature the tunnel experiences?
