Ice volcanoes have formed again along the shores of Okanagan Lake in Penticton. An ice volcano is a conical mound of ice formed over a lake via the eruption of water and slush through an ice shelf. The process is wave-driven, with wind providing the energy for the waves to cut through the ice and form the so-called volcanoes. The liquid water and slush freeze and fall back to the surface, growing the formation.
