The Piramidi di
Postalesio, or Pyramids of Postalesio, are
extremely unusual and very intriguing. This phenomenon is of great interest both from the perspective of the flora and fauna and
with respect to the landscape itself, since it only occurs in conjunction with
a unique series of geological, environmental and climatic factors. Erosion
occurs as the rainwater falls onto the earth, crumbling and carrying away the
soil so that only the compact boulders remain. Thus, columns carrying large
boulders of varying dimensions are “born”. The process is ongoing
and next to the existing columns a number of new formations are starting.
The small valleys that form around the
pyramids create a unique microclimate
that has favoured the growth of a dense forest in which both cold-climate
species, such as larches, European spruce and Scots pine, and species that
prefer warmer climates cohabit.
