Amazing what some warm weather can do. The Assiniboine River in Winnipeg.
The big melt is underway in Manitoba. The Assiniboine River has substantially risen in the last few days. The current is hauling the broken ice on the Assiniboine into the Red River in downtown Winnipeg.
Crystal like ice that looks pretty cool
Lake Hillier is a saline lake on the edge of Middle Island, the largest of the islands and islets that make up the Recherche Archipelago in the Goldfields-Esperance region, off the south coast of Western Australia. It is particularly notable for its pink colour. A long and thin shore divides the Southern Ocean from the lake.
Lake Hillier is about 600 metres (2,000 ft) in length by about 250 m (820 ft) in width. The lake is surrounded by a rim of sand and a dense woodland of paperbark and eucalyptus trees with a narrow strip of sand dunes covered by vegetation separating its northern edge from the northern coast of Middle Island. The most notable feature of the lake is its pink colour. The vibrant colour is permanent, and does not alter when the water is taken in a container. The pink colour is considered to be due to the presence of the organism Dunaliella salina. Air is the best mode of transportation for viewing the lake. At one point in its history the lake was used to collect salt.
Lake Hillier was visited by the Matthew Flinders’ expedition on 15 January 1802. Flinders’ journal entries are considered to be the first written records of the lake. Flinders observed the pink lake after ascending the island’s highest peak (now called Flinders Peak), describing the lake as follows:
In the north-eastern part was a small lake of a rose colour, the water of which, as I was informed by Mr. Thistle who visited it, was so saturated with salt that sufficient quantities were crystallised near the shores to load a ship. The specimen he brought on board was of a good quality, and required no other process than drying to be fit for use.
Flinders visited Middle Island again in May 1803; he intended “to stop a day or two in Goose-Island Bay, for the purposes of procuring geese for our sick people, seal oil for our lamps, and a few casks of salt from the lake on Middle Island”. It is reported that Flinders subsequently named the lake after William Hillier, a crew member of Investigator who died of dysentery on 20 May 1803 prior to the expedition’s departure from Middle Island.
In 1889, Edward Andrews investigated the commercial possibilities of producing salt from Lake Hillier, and briefly moved onto the island with both of his sons. They left after working the salt deposits for about one year.
The lake was subject to salt mining during the late 19th century. The salt mining enterprise is reported as failing for a number of reasons including “the toxicity of the salt collected for consumption”.
The only living organisms in Lake Hillier are microorganisms including Dunaliella salina, which causes the salt content in the lake to create a red dye which helps produce the colour, as well as red halophilic bacteria present in the salt crusts. Despite the unusual hue, the lake exhibits no known adverse effects upon humans. From above, the lake appears a solid bubble gum pink, but from the shoreline it appears more of a clear pink hue. The shoreline is also covered in salt crust deposits.
Despite the high salt content levels (comparable to those of the Dead Sea), Lake Hillier is safe to swim in. However, there are very few ways to reach Lake Hillier. Aeroplane scenic flights are the most common method, with 6 flights a day departing Esperance Airport, flying over Lake Hillier via the nearby Cape Le Grand National Park. Cruises are also an option for passengers wanting to visit the isolated lake, and surrounding forest area.

Scientists have discovered a previously unknown “supercolony” of more than 1.5 million rare penguins on an island located off the Antarctic Peninsula. The researchers from Stony Brook University discovered the enormous colony of Adelie Penguins after analyzing satellite imagery of the island. The population of Adelie Penguins had been previously thought to be in decline.
Lenticular clouds (Altocumulus lenticularis in Latin) are stationary clouds that form in the troposphere, typically in perpendicular alignment to the wind direction. They are often comparable in appearance to a lens or saucer.
Because of their unique appearance, they have been brought forward as an explanation for some unidentified flying object (UFO) sightings.
