You’ll find that the theory of glacial lakes maintaining year-round ice coverage depends entirely on elevation and latitude, not just surrounding temperatures.
These frozen sanctuaries, from Australia’s Blue Lake to Nepal’s Tilicho, challenge what you’d expect about liquid water’s persistence in extreme environments.
Each lake’s transformation follows unique patterns that scientists can’t fully predict, and the reasons why some freeze completely while others don’t will surprise you.
Blue Lake, Snowy Mountains, Australia
Nestled within Kosciuszko National Park, Blue Lake stands as one of mainland Australia’s four glacial cirque lakes, carved from granite bedrock at an elevation of 1,890 meters above sea level.
You’ll find this 16-hectare alpine treasure frozen from June through October, its 28-meter depths preserving ancient glacial heritage.
The lake’s water level remains stable year-round except during spring when snowmelt overflow causes temporary fluctuations.
As a Ramsar-listed wetland, it’s protected habitat for endangered species like the mountain pygmy possum.

Lake Cootapatamba, Kosciuszko National Park, Australia
Perched at 2,048 meters above sea level, Lake Cootapatamba claims the title of Australia’s highest lake, sitting just 800 meters south of Mount Kosciuszko’s summit.
You’ll find this post-glacial tarn stretches 400 meters long with depths reaching five meters. The lake serves as a popular destination for hikers and nature photographers exploring the high country.

Hedley Tarn, Australian Alps
A crystalline mirror of water sits at the heart of Kosciuszko National Park’s alpine wilderness, where Hedley Tarn forms one of Australia’s most pristine glacial lakes at an elevation exceeding 1,800 meters.
You’ll find this shallow five-meter-deep tarn frozen for four months annually, surrounded by rare alpine species like mountain pygmy possums and snow-wort.
Its ultra-fresh waters contain just three grams of salt per cubic meter.

Club Lake, Main Range, Australia
Further north along the Main Range, Club Lake forms another significant glacial remnant where ancient ice carved deep basins into the Australian Alps’ highest peaks.
You’ll find this rare glacial lake near Club Lake Creek’s confluence with the Snowy River, accessed via the challenging Main Range Walk from Charlotte Pass.
The surrounding alpine terrain showcases Australia’s unique glaciation history through its carved rock basins.
Lago Argentino, Patagonia, Argentina
Where the Southern Patagonian Ice Field meets the Argentine steppe, Lago Argentino sprawls across 1,560 square kilometers as South America’s third-largest lake and Argentina’s most extensive body of freshwater.
You’ll find this turquoise giant fed by Perito Moreno and Upsala glaciers, creating dramatic ice-calving displays. Its glacial milk suspension gives the water its distinctive color, while depths plunge to 1,000 meters in certain areas.
Lago Viedma, Southern Patagonian Ice Field
While Lago Argentino captures most visitors’ attention, Lago Viedma stretches 80 kilometers through Santa Cruz province as Argentina’s second-largest perennial lake, fed primarily by the country’s most extensive glacier.
You’ll find this elongated trough lake receives massive ice calvings from Viedma Glacier, whose 40-meter-high terminus spans two kilometers.
The glacier extends from the Southern Patagonian Ice Field, Earth’s largest continental ice mass outside Antarctica.
Jökulsárlón Glacier Lagoon, Iceland
Moving from Patagonia’s ancient ice fields to Iceland’s dynamic glacial landscapes, you’ll encounter Jökulsárlón Glacier Lagoon—a remarkable body of water that didn’t exist before 1935.
You’ll witness thousand-year-old icebergs floating across Iceland’s deepest lake, where freshwater meets seawater creating milky-blue colors.
Seals navigate between the ice formations while northern lights illuminate winter skies above this 25-square-kilometer lagoon within Vatnajökull National Park.
Lake Louise, Canadian Rockies, Alberta
Princess Louise Caroline Alberta never saw the turquoise waters that bear her name, yet you’ll find her legacy preserved in one of Canada’s most photographed alpine lakes.
At 1,731 meters elevation, Lake Louise‘s brilliant color comes from glacial rock flour suspended in meltwater.
You’ll discover this 2.4-kilometer jewel nestled between Mount Victoria and Mount Temple, where the Fairmont Chateau crowns its eastern shore.
Moraine Lake, Banff National Park, Canada
Photography buffs call it the “Twenty Dollar View,” though Canada removed this glacial masterpiece from its currency in 2012.
You’ll find Moraine Lake‘s turquoise waters in Banff National Park, where glacial rock flour creates its signature color.
The lake remains frozen until June, when snowmelt reveals waters surrounded by the Valley of the Ten Peaks.
Grinnell Lake, Glacier National Park, Montana
Turquoise waters mark your arrival at Grinnell Lake, where glacial meltwater tumbles down from Mount Gould’s northern slopes.
You’ll find this pristine lake at 5,040 feet elevation, fed by the retreating Grinnell and Salamander glaciers. Rock flour suspended in the water creates its distinctive color.
The easy seven-mile roundtrip trail offers you spectacular views of waterfalls, surrounding peaks, and wildlife including grizzly bears and mountain goats.
Iceberg Lake, Glacier National Park, Montana
Shadows from towering peaks keep Iceberg Lake frozen well into summer, where you’ll discover floating ice chunks drifting across turquoise waters at 6,094 feet elevation.
You’ll hike 9.6 miles round-trip through wildflower meadows beneath the Ptarmigan Wall’s 1,500-foot cliffs.
Mount Wilbur rises 3,000 feet above the lake’s surface, creating the alpine cirque that traps cold air and preserves ice year-round.
Lac Blanc, French Alps
A crystalline mirror reflects Mont Blanc’s summit when you reach Lac Blanc at 7,716 feet, where two connected alpine pools rest within the Aiguilles Rouges Nature Reserve above Chamonix Valley.
You’ll hike steep, rocky trails from La Flégère cable car station, gaining 1,700 feet over two miles. Protected regulations prohibit swimming to preserve this fragile ecosystem, where snow often lingers year-round across the pristine waters.
Oeschinensee, Swiss Alps
Descending from France’s high alpine terrain into Switzerland’s Bernese Oberland, you’ll discover Oeschinensee resting at 5,177 feet within a dramatic mountain basin four kilometers east of Kandersteg.
