End-time Prophecy
This "sinkhole" appeared in Guatemala in
2010. It shares
none of the characteristics of
the
actual real sinkholes shown below.  
The sides are rifle bore smooth.

Revelation 9:2  And he opened the bottomless
pit
; and there arose a smoke out of the pit, as
the smoke of a great furnace; and the sun and
the air were darkened by reason of the smoke
of the pit.
