I'd be very concern if more natural wonders around the world crumble into dust as well.
Call this a sign of impending DOOM!
Once the TWO POPES die, then things will get scary for everyone:
"I didn't see, I don't see any Great Pope or Great Monarch before an extremely great tribulation, horrifying, terrible and general for all Christendom. But before that time, twice there will be a short lived peace; two shaky, servile, doubtful popes" Melanie
After the TWO POPES die:
God will abandon mankind to itself and will send punishments which will follow one after the other for more than thirty-five years. Our Lady of La Salette 19 Sept. 1846 (Published by Mélanie 1879)
But before this start of the 35 year period of chastisements, I do think that there will be some events leading up to the death of the TWO POPES.
Two arches & Two Popes
One arch down.
This collapse of the archway on the Atlantic Coast is just the beginning.
And he stood upon the sand of the sea.
Rock archway collapses on to beach in Morocco
One of two rock archways at Legzira beach on Morocco’s Atlantic coast has collapsed. A pile of red rubble was all that was left after the natural wonder near the city of Sidi Ifni, 93 miles (150km) south of Agadir, came down on Friday afternoon. Often cited as one of the world’s most beautiful beaches, Legzira is famous for sunsets punctuated by the rock structures jutting out from the cliffs. They were formed over thousands of years by erosion. It is not known what caused the collapse, but the movement of the sea could be a factor. A large crack appeared on the southern face of the arch in March after a chunk of it fell off, Ifnipress reported. The second, larger arch remains standing further along the beach. The loss of the arch may have an impact on Morocco’s tourism sector, which saw a fall in overseas visitors in the first half of 2016. Fears of terrorism and regional instability are thought to be to blame for a decline in tourists heading to the main destinations of Agadir and Marrakech. Guardian
