Lightning Peak is a summit in the Midway Range of the Monashee Mountains, British Columbia, Canada. It is an eroded volcanic outcrop in the Chilcotin Group. The mountain is located 30 km (19 mi) west of Needles, and 70 km (43 mi) east of Downtown Kelowna. Peridot can be found at this peak. Lightning Peak is thought to have formed as a result of extension of the crust behind the coastal subduction zone and last erupted during the Pliocene. Like most volcanoes in British Columbia, Lightning Peak is part of the Pacific Ring of Fire, that includes over 160 active volcanoes.
