60 million years ago, Erciyes, Hasandağı, and the intervening Göllüdağ, with their volcanic activity, deposited layers of ash, forming a soft tuff layer in the region. The tuff layer was intermittently covered by a thin layer of hard basalt in some areas.

Rainwater began seeping through the cracks, gradually eroding the soft tuff. The process was further aided by the warming and cooling of the air, and winds also played a role in the formation. As a result, cones with hats made of hard basalt rock emerged. The local people bestowed a name upon these unique and interestingly shaped rocks: ``Fairy Chimneys.``
