Mushrooms of Rezzago
Geological formations resembling mushrooms created when water running off the slopes was diverted by large boulders. The boulders imposing size and weight protected the underlying material from erosion and gave rise to the characteristic shape of a column of compacted rocks and earth capped by a large a boulder. Over time, as the height of structures grew, they became subject to being thinned out and collapsing as happened to one of the four examples on site. Visitors can note a new mushroom just starting to grow.
