Climber Style Ascent Date Suggested Grade

With a parachute so he could base jump off the route in case the solo didn't go to plan!

Potter soloed pitches 5–8, including the top 7b+ pitch. To gain enough height to make a parachute fall viable, Potter traversed in to midway through pitch 5, avoiding sustained hard climbing (up to 7b+) lower down; he did not solo the easy top pitch due to rain.
