Situated at an elevation of 550 m, Uisangbong Peak features various weathering landforms including gnamma (also known as ‘panhole’ or ‘weathering pits’ - a depressed, erosional feature resulted of weathering and generally seen on bedrock) and tor (a large, free-standing rock outcrop that rises abruptly from the bedrock as a result of differential erosion). Particularly, the gnammas are spread over Eusangbong Peak and feature depths of 170 cm or deeper. The namess for the weathering landforms include Bimajokbawi, Byeoroobawi, Eusangdae, and Beyongpung Sinseondae.
