 Kostal Cone is too young for the potassium-argon dating technique (usable on specimens over 100,000 years old), and no charred organic material for radiocarbon dating has been found.However, the uneroded structure of the cone with the existence of trees on its flanks and summit have made it an area for dendrochronology studies, which reveals the growth of tree-ring patterns.Tree-ring dating has revealed an age of about 400 years for Kostal Cone, indicating it formed around 1500.
