Evidence of Prehistoric cultures in Cappadocia can most easily be found around Köskhöyük/Nigde, Asiklihöyük/Aksaray and in the Civelek cave near Nevsehir. Excavations in these three areas are still taking place. |
Fairy chimneys are generally found in the valleys of the Uçhisar-Ürgüp-Avanos triangle, between Ürgüp and Sahinefendi, around the town of Çat in Nevsehir, in the Soganli valley in Kayseri, and in the village of Selime in Aksaray.
Another characteristic feature of the area are the sweeping curves and patterns on the sides of the valleys, formed by rainwater. These lines of sedimentation exposed by erosion display a range of hues. The array of color seen on some of the valleys is due to the difference in heat of the lava layers. Such patterns can be seen in Uçhisar, Çavusin/Güllüdere, Göreme/Meskendir, Ortahisar/Kizilçukur and Pancarlik valleys.

Mount Erciyes, Hasandag and Göllüdag were active volcanoes in the geological periods. Alongside with many other volcanoes, eruptions of these volcanoes started in the Early Miocene (10 million years ago) and hava continued until the present day.
The lava produced by these volcanoes, under the Neogen lakes, formed a layer of tufa on the plateaus which varied in hardness and wass between 100 and 150m thick. Other substances in the layer are ignimbrite, soft tufa, tufa, lahar, ash, clay, sandstone, marn, basalt and other agglomerates.

Plateaus, having been essentially shaped with the lava from the bigger volcanoes, were continuously altered with the eruptions of smaller volcanoes. Starting in the Early Pliocene Period, the rivers in the area, especially Kizilirmak (the Red River), and local lakes contributed to the erosion of this layer of tufa stone, eventually giving the areaits present day shape.
