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.
Ice volcanoes erupted during last February’s cold snap but before that Penticton hadn’t seen them since 2019.
Most of B.C. is experiencing a deep freeze with Summerland breaking a temperature record on Monday at -22.4 C.
This broke Summerland’s previous record of -20.6 set in 1971.
Penticton also set a new record of -20.6, according to Environment Canada. The last record of -19.4 was set in 1968.
Records in this area have been kept since 1907.
This December’s cold snap has even caused ice to form on the Penticton Channel.
A video has surfaced of people taking an early Polar Bear plunge into Skaha Lake on Boxing Day.
Steam devils – twister-like events that form above a lake were filmed and photographed in Summerland and Vernon on Monday, Dec. 27. Cindy Whitford filmed what she called a polar vortex water tunnel form into a twister above Okanagan Lake in Summerland. The twister moved towards Penticton.
The air is colder than the lake water, creating rising steam.
A steam devil is a small, weak whirlwind over water that has drawn fog into the vortex, thus rendering it visible. They form over large lakes and oceans during cold air outbreaks while the water is still relatively warm.
