Jinburyeong (529m above sea level) is a major mountain pass to cross east-west direction of the Taebaek Mountains, connecting between Buk-myeon, Inje-gun and Ganseong-eup, Goseong-gun. The Jinburyeong is the lowest peak in the middle part of the Taebaek Mountains and the best spot to see the difference in the inclination of the slopes in the east and the west of the ranges which are asymmetric due to the tilted upwarping. It is asymmetric in shape since its west slopes toward Inje are gentle while its east slopes toward Goseong are relatively steep This phenomenon is due to the tilted upwarping in the Tertiary, the event that the Korean peninsula was uplifted by the expanded oceanic crust of the East Sea under horizontal compression. The position of the uplift axis was tilted toward the east, resulting in steep slopes in the east but gentle slopes in the west, i.e., an asymmetric cross-section. Including the Taebaek Mountain Range, all the mountain ranges of Korea stretching from north to south or east to west are asymmetric, which is typical of the geography on the Korean peninsula. The name Jinburyeong came from Jinbu ‘Won’ (public inn for travelers on official duties during the Joseon Period) which used to be located where the Jinburyeong today is. It was a major traffic route between the Yeongdong region and Yeongseo region in Gangwon Province together with Mishiryeong (Inje-Sokcho), Hangyeryeong (Inje-Yangyang), Daegwanryeong (Pyeongchang-Gangneung), and Baekbongryeong (Jeongseon-the East Sea) until Yeongdong Expressway opened in 1975 and railroads such as Yeongdong Line and Taebaek Line were completed.
