Why is Bear Lake so blue?
Bear Lake contains abundant suspended microscopic particles of white-colored calcium carbonate (lime) that reflect the water’s natural blue color back to the surface, giving the lake its intense turquoise-blue color. This color is why Bear Lake is known as the “Caribbean of the Rockies.”
What causes frozen bubbles in Abraham Lake?
Abraham Lake’s frozen bubbles are caused when plants and tree limbs on the bottom of the lake start decaying. During this process methane gas is released, creating bubbles in the water.
Why is Lake Tahoe so blue?
What makes Lake Tahoe so spectacularly blue? The cobalt color was long attributed to the unusual clarity of the water in the lake, which is located along the California-Nevada border. But surprising new research suggests that the real explanation lies with algae that live in the lake.
Why are lakes bluer when algae are low?
The bluer the lake, the lower the clarity of its water. The lake is actually bluest when algae concentration is low. The finding suggests that the need for a change in conservation efforts, which traditionally have focused on controlling sediment to keep the lake water clear.
What is so unusual about Lake Abraham?
Despite being artificial, Abraham Lake still resembles other glacial lakes in the region, with the distinctive turquoise water that is caused by sediments of glacial erosion entering the lake, giving it unique coloring.
What causes the bubbles at Abraham Lake?
Abraham Lake's frozen bubbles are caused when plants and tree limbs on the bottom of the lake start decaying. During this process methane gas is released, creating bubbles in the water.
Can you swim in Abraham Lake?
Forget boating and swimming as the lake is very cold and the high winds can generate large waves.
Why does Abraham Lake have methane bubbles?
Abraham Lake was created in 1972 when the North Saskatchewan River was dammed drowning a large amount of organic material which creates methane gas as it decomposes. In addition, deposits of methane hydrate, currently frozen at the bottom of the lake in permafrost, release methane gas as the permafrost thaws.
Is it safe to walk on Abraham Lake?
That area has some of the least stable ice on the lake, with conditions changing on a daily basis. It's possible to have a safe ice walk there but it does require more experience and a better understanding of the ice conditions than other locations on the lake we would recommend.

What type of lake is Abraham Lake?
artificial lakeAbraham Lake, also known as Lake Abraham, is an artificial lake and Alberta's largest reservoir.
How do frozen bubbles occur?
Trapped methane causes frozen bubbles to form under the ice on the lake's surface. This phenomenon results when decaying plants on the lake bed release methane gas, which creates bubbles that become trapped within the ice, in suspended animation, just below the surface as the lake begin to freeze.
What are methane bubbles?
Bubbles filled with methane rise when released. The rising bubbles are set on fire with a candle on a stick to demonstrate the combustion reaction.
What are frozen air bubbles?
Abraham Lake is home to a rare phenomenon where bubbles get frozen right underneath its surface. They're often referred to as ice bubbles or frozen bubbles. This has made the lake famous among photographers.
What are ice bubbles?
It starts when bacteria feed on decaying plants and animals that have collected along the lake bottom. That process releases methane gas in the form of thousands of bubbles. Floating to the water's surface, the bubbles remain trapped in frozen, suspended stacks until spring thaw.
What is the water color of Abraham Lake?
Abraham Lake is stunning in every season, but it really dazzles in the winter when its turquoise water freezes to reveal thousands of white bubbles below the surface.
What does Abraham Lake look like?
Soon the lake looks like a giant lava lamp, with icy blobs frozen in time. Even though all lakes have organic matter decaying in their depths, what makes Abraham Lake such a special place to see frozen methane bubbles is the clarity of the ice and high concentration of bubbles.
What happens to methane in Abraham Lake?
As Abraham Lake continues to freeze, stacks and layers of bubbles start to appear in the thickening ice.
Why are there bubbles in Abraham Lake?
Bubbles frozen into a wall of ice in Abraham Lake. Abraham Lake’s frozen bubbles are caused when plants and tree limbs on the bottom of the lake start decaying. During this process methane gas is released, creating bubbles in the water.
What color are the bubbles in Preacher's Point?
Since the lake is deeper here than at the Preacher’s Point, the water is a dark blue-green which really makes the ice bubbles stand out.
Why does Abraham Lake rise and fall?
Since a dam controls the water level of Abraham Lake, it can rise and fall even after ice forms on the top . When there’s an air gap between the ice and water, the ice can break more easily. Someone who falls through might not be able to pull themselves out of the water because the ice is beyond reach (plus shock sets in from the cold).
Where to see ice bubbles in Abraham Lake?
These areas typically can be found south of Windy Point.
Why is Bear Lake called the Caribbean of the Rockies?
Beautiful Bear Lake is called “the Caribbean of the Rockies” because of its vivid turquoise-blue water, but why is Bear Lake so Blue? A new booklet published by the Utah Geological Survey answers this and 16 other commonly asked questions about the lake.
How many pages are there in the Bear Lake booklet?
The 41-page booklet is filled with dozens of photographs, maps, and figures. It contains information on geology, biology, hydrology, weather, recreation, history, the Ice Age, the modern and prehistoric connection to the Bear River, and laws and regulations governing the use of the lake. Those with a keen eye might even spot the mysterious Bear Lake Monster hidden within its pages.
What color is Bear Lake?
Bear Lake owes its vivid blue color to clean, deep, calcium-carbonate-rich water. View is to the east with Bear Lake Plateau towering in the background.
How was Bear Lake formed?
area’s complex geologic structure. The basin holding Bear Lake was created by vertical movement on the eastern Bear Lake fault (a fault is a break in Earth’s crust along which blocks of rock and sediment slip past each other, causing earthquakes). The movement on the eastern Bear Lake fault is mostly vertical where the Bear Lake Valley moves down relative to the rising Bear Lake Plateau and Preuss Range. The fault is not actually a single discrete break but a zone with multiple fractures. Top image from Google Earth.
What causes the formation of Bear Lake?
A long history of recurring fault movements and resultant earthquakes created the basin that holds Bear Lake, and thus created the lake (just add water). Tectonic forces within Earth’s crust have been stretching the Bear Lake Valley in an east-west direction for perhaps 10 million years or more. Fault movement along the eastern Bear Lake fault, as well as lesser faults such as the western Bear Lake fault, release this tensional stress. Along the eastern margin of the Bear Lake Valley, the eastern Bear Lake fault acts as a geologic escalator, lowering the valley floor and lake bottom relative to the rising Bear Lake Plateau and Preuss Range. The total offset between valley and mountain has been approximately 12,300 to 16,700 feet. The topographic relief is much smaller today because erosion slowly, but relentlessly, wears down the Bear Lake Plateau and Preuss Range while filling the valley and lake bottom with sediments.
How did Bear Lake separate from the Bear River?
The open- and closed-basin scenarios produced different water chemistries, which are recorded in the lake- bottom sediments. This is largely due to the Bear River delivering distinct minerals and chemicals to the lake. Bear Lake retracted and was separated from Bear River for relatively short time intervals over the past 220,000 years. The earliest occurred 207,000 years ago and subsequent separations happened between 187,000 and 192,000 years ago, 111,000 and 124,000 years ago, about 103,000 years ago, and for the most of the past 15,000 years, except for a brief interval between about 8,500 to 7,000 years ago. Never during this time did the lake come close to drying up, implying there was always a significant inflow of ground water. Scientists used various forms of evidence in the sediment core to reconstruct this history. For example, the presence of the mineral aragonite (a form of calcium carbonate) appears during the closed-basin intervals and implies warm and dry climatic conditions. During open-basin intervals, core data revealed that the lake-river connection usually occurred during wetter and colder climate when the lake expanded. However, the river and lake can join independent of climate, complicating the picture. For instance, when the Bear River meanders southward it can join the lake, without requiring a change in climate or lake level.
What is the magnitude of the Bear Lake fault?
The eastern Bear Lake fault is capable of generating earthquakes as large as magnitude 7.4. The largest historic earthquake that shook the valley, the November 10, 1884, Bear Lake earthquake, had an estimated magnitude of 6.3.
How wide is Bear Lake?
At a maximum historic surface elevation of 5,923 feet, the lake is 20 miles long and more than 7 miles wide with a shoreline length of roughly 48 miles and a maximum depth of 208 feet. It is situated in the southern half of the nearly 50-mile-long and 5- to 10-mile-wide Bear Lake Valley.
Why is Bear Lake important to scientists?
Over the past few decades, Bear Lake has been intensely studied because it is one of the oldest lakes in North America, has not dried up during extended warm and dry climates (unlike many other lakes), and is in an area sensitive to changes in regional climate patterns. Therefore, Bear Lake research helps us to understand past climates and environments of this area, and by extension the intermountain region, as well as understand the lake itself. Because the Bear River, the main tributary of the lake, has alternated between flowing into the lake and bypassing the lake, recent studies have also provided time frames on when these conditions occurred, if and when the lake grew to fill the entire Bear Lake Valley or shrank into the southern part of the valley, and if climate forced these changes. In a culmination of much of their research, the U.S. Geological Survey and a team of other scientists published 14 technical reports in a 2009 book titled
Why is CaCO3 blue?
This allows the pH to rise and for Calcium Carbonate to precipitate. The CaCO3 is very finely crystalline and remains suspended in the water column giving it that "Bahamian" blue color. If that is volcanic lake, the same process can be at work.
What happens when a volcanic lake is exposed to air?
If that is volcanic lake, the same process can be at work. CO2 rich fluids are permeating the surrounding rock dissolving minerals and once the water is exposed to air the CO2 degasses and acid soluble minerals precipitate.
What is the effect of quarry water?
This would appear milky white in a small amount of water, but in a deep quarry, like those in many images, the effect is to amplify the naturally blue appearance of the water in sunlight.
Why is Lake Tahoe blue?
