The World of Mountain Meadows
Legacy of Glaciers
The last ice age and its traces in the landscape
In the ice age, Jeseníky mountains were a kingdom of snow and ice. The snow
layer was thicker in the lee – an ideal place for glacier formation. The
weight of ice, growing every year, was pressing on the ground beneath it and,
together with frost effects, hollowed out basins and new valleys. The most
significant one is called Velká Kotlina („Great Basin“). Frost is powerful
enough to break rocks, and on the ridge you can see solitary rocks resisting to
frost – mrazové sruby. Stone seas form under them. Frost can also play with
stones, it sorts them and assembles them into interesting images. Small stones
and gravel are left in place, while big stones are rolled to the edge of the
surface. As a result, regular polygonal structures are formed in the ground.
There are usually hardly visible in Jeseníky, as they are covered with alpine
grasses. However, you can still admire them on the peak called Pecný. By
re-arranging stones, you damage unique natural phenomenons created by frost.
