Abstract: Study of the geomorphological features of an area in Northern Anatolia furnished some critical data tobetter understand Quaternary development of Northern Anatolia. Investigation of numerous river terraces leads to theconclusion that the area suffered severe epeirogenic movements during Quaternary. The presence of a heavily dissectedold peneplain has been proven. The presence of the valey slopes strongly convex upward ,and the summit plains also indicate the important role played by epeirogenic movements in Quaternary shaping of the area.Geomorphological map of the studied area was accomplished during the present study.
