The Cappadocia region has some classic differential weathering features in a volcanic ash that have been used for human uses and today supports a major tourism area in Turkey. The following picture is the common postcard depiction of the towers (fairy chimneys).
One of three volcanoes in the area responsible for the ash.
Variations in ash composition produces layering visible in the towers (different volcano sources or various in eruptive material from same volcano?).
Erosional towers are not the only ones in region. These towers are used to dry animal dung for fuel supply.
