Mount Thor, officially gazetted as Thor Peak, is a mountain with an elevation of 1,675 metres (5,495 ft) located in Auyuittuq National Park, on Baffin Island, Nunavut, Canada. The mountain is located 46 km (29 mi) northeast of Pangnirtung and features Earth’s greatest vertical drop of 1,250 m (4,101 ft), with the cliff overhanging at an average angle of 15 degrees from vertical. Despite its remoteness, this feature makes the mountain a popular rock climbing site. Camping is allowed, with the only official site being at the entrance to the Akshayuk Valley near Overlord Peak.
I don’t know about climbing it, maybe a parachute jump from the top.
