Incesu break-through valley is situated between Incesu village, Ortakoy-Corum and Kazankaya village Aydincik-Yozgat. It is an epygenic break-through valley formed by the river Cekerek. The average river bed inclination is about % 35 and it is formed on Jura-Cretase landscape with curls. Through the total length of 8 km the height of the valley is approximately more than 500 m. In the valley an asymmetry is seen related to the structure of the land and the pedestals. Furthermore, the bottom of the valley widens in few places. It is very difficult to make agricultural activities in the valley. It is thought that rafting and alpinism can be done if necessary organizations made.
