Large Gogotte De Fontainebleau

Large gogotte de Fontainebleau. A gogotte is a beautiful example of art made by nature. Gogottes” are natural creations formed out of sands deposited in Northern France during the Oligocene Period, approximately 30 million years ago. Much later, in a process that has only recently become understood, groundwater rich in silica flowed through the sands, creating swirling organic shapes and cementing the sand into the fluid forms that we see today. This geological process took place during two cold periods of the Quaternary—one approximately 300,000 years ago, the other more recent, during the last glaciation, between 30 and 50,000 years ago.
