Stalactite Ice on the Kananaskis River, AB (Canada), Feb. 20, 2013
The Kananaskis River in Alberta is regulated for hydro-power production, with water levels varying up to 1 m (~3 ft) each day. As the water level drops, ice is left stranded at higher levels, and this combined with some melting on warm days, creates some beautiful and peculiar ice formations. In February 2013, the River Ice Group grad students came across these beautiful ice stalactites on the underside of a perched ice shelf.
