The purpose of this study is to analyse the geological and terrain factors of the part of Choogaryeong Rift Valley between Yeoncheon and Cheolwon. The results are: (1) The geology is composed of three kinds of rocks: Yeoncheon System, Jurassic volcanic rocks and Quaternary Jeongok basalt. (2) It seems to be that there are basaltic layers of 7-8m thickness below the rift valley by the analysis of resistivity survey. (3) The topography of the region could be divided into two characteristic parts: the rift valley and surrounding mountainous area. (4) The site of the area is important because it is the boundary where two kinds of different geologic factors contact. (5) The situation of the area is important because of its central location between Seoul and Wonsan.
