"Here's some interesting information about the Formation of Lake Garda"
The Formation of Lake Garda
Lake Garda was created in the Quaternary Ice Ages 1.5 million years ago...so it's a very old lake!
It was formed by a massive piedmont glacier that flowed down from the Brenta Dolomites, cutting
through and gouging out the valley. 'Piedmont' basically
means a valley glacier that has spilled onto adjacent flat land. This is the reason Lake Garda is
an axe shape, because the ice spread onto the flat land as it came out of the valley. Eventually
the ice glacier melted, resulting in the freshwater lake it is today.
So why is Lake Garda so fertile? Well, the as the glacier moved through the valley, it ground up
loose magnesium-rich limestone into
a paste, which was deposited as moraine along the sides of the ice. When the glacier melted, the
moraine resulted in the rich fertile soil found along the shores of Lake Garda. So that's why the
fruit, olives and wine produced from the rich soil around Lake Garda are so full of flavour!
