Do you expect anyone to believe that a collapse of a small cavern in that bedrock could effect the surface with a sinkhole?
Who said it was small? Or that there was just one? Do more (or even some) research.
I'll also remind you that the soil is very hard clay, so strong that the treasure pit required no caging whatsoever to prevent the walls from collapsing.
What happens when clay gets saturated? Twice a day? Repeatedly? Over millions of years? Clay-type soils over limestone karst can result in a type of sinkhole called a cover-collapse sinkhole, the edges of which erode over time.
There is no way a sinkhole could form on the east end of Oak Island and that is simple geological fact.
Is that real science or Brian-science (like the kites that don't flutter in the breeze that the Rosicrucians have been keeping secret all these years? Oak Island is clay over limestone - limestone dissolves, clay spalls into the cavities, ground collapses - that is geological fact.
That's how we KNOW that the cave in pit formed directly over the path of the flood tunnel was due to said tunnel and not a natural sinkhole.
So much for the lame brain theories of Le Popol, Mark H, and the aptly named Dick Joltes and Joe Nickell!
Except that the only recorded scientific survey of the island found no geophysical evidence of the tunnel. The pit floods because it's below the water-table. Given that the highest point on the island is 35ft, hitting water in a 160-foot deep hole is a no-brainer.
