线路 in Telemark for selected grade

Serious business. Originally an aid line (C2) named after the local geology, then freed by Martin in 2015. The free version starts from the ledge above Diederet, goes up to the break, then traverses right into the crackproper. Straight up the unrelenting crack until it terminates then traverse left and up the arête to run it out 8m to the top. The aid version starts 10m below. Start as for Diederet then move right to the thin seam. The original(?) belay bolts at the end of the finger crack were removed for the FFA rendering the aid finish undetermined. According to the 2007 Telemark guide the aid route follows the same path as the free route out left to the arete, apparently on bathooks.
