Chalk: The white cliffs of Møn…

The Danish island Møn provides a beautiful scenic coastal landscape with green and lush forests on top of high white cliffs of chalk, with pebbly shores and the blue Baltic Sea beneath. It is also a great excursion locality if you want to study Cretaceous to Paleogene chalk, or natural erosive processes along coastal cliffs such as slumping or mudflows.

To get to the shore you have to descend down a path, partly as stairs with multiple steps.

Descending through the lush forest...

 The beach is covered with flintstone pebbles in various grey colors and sizes. Numerous trees have fallen down the slopes and their trunks are weathered white from the sea.

The cliffs are 140 meters high at the highest point. Screes are common and sometimes the shore is closed due to risk of landslides.

The chalk consists of billions of fragments of calcareous nannoplankton, coccolithophorids, that thrived in the warm Cretaceous Sea along with sharks, mosasaurs, fishes, ammonites and lots of other organisms.
 
 
I highly recommend a visit to Møn and to Geocenter Møns Klint – a wonderful exhibition centre presenting the geology of Denmark with specific focus on the chalk, and the environment and wildlife of Møn.
