STRANGE BUT TRUE!   23

         Meaning “where one cannot walk,”
        Grand Tsingy is an isolated wilderness           FAST FACTS
         in Madagascar’s Tsingy de Bemaraha
      national park. Its limestone rock has been
        eroded into a grid-like pattern of dead-
     straight canyons called grikes, topped with
       dangerously craggy spears. Though the
     entire area appears gray rather than green,
       plant life flourishes between the peaks.





 The canyon walls                                      Groundwater flowing along
 are up to 328 m                                       fracture lines in the rock cut
 (100 ft) tall.                                        caves in the limestone of Grand
                                                       Tsingy, while monsoon rains
                                                       eroded the surface.







                                                       Over millions of years the water
                                                       continued to erode the caves,
                                                       causing them to expand and
                                                       merge into deep, narrow
                                                       underground caverns.







                                                       The cave ceilings then collapsed,
                                                       exposing the network of towering
                                                       canyons we see today, topped
                                                       with sharp peaks carved by
                                                       surface erosion.
