Corner Crack(코너크랙)

This is most beautiful sustained lie backing crack in Korea.

Approaching Seoninbong, ignore the Seokgulam Temple visible along the trail and continue to follow the hiking path. As you climb the stone steps towards Jaunbong, you will see a no-entry sign on your right. Behind it, you can reach the so-called Titanic Rock with a bit of scrambling over the 5th terrain. This spot serves as a hub for accessing all routes on the south face of Seoninbong. To climb the Corner Crack route, you need a rappel rope and a climbing rope. Using a 70m climbing rope allows for safe top-roping. While rappelling from the anchor installed at the edge of Titanic Rock, you should pre-clip the climbing rope. Because chimney part is huge runouts. At the start of the crack, use a #0.3 and #0.2 Camalot for equalizing. There’s an old piton which you can back up with a quickdraw for added safety.

Single .2, .3, quickdraw for pre-clipping to avoid runout chimney. Double .4, .5, .75 for crack
