What You'll Learn
Candle ice is a form of rotten ice
Candle ice, also known as candlestick, needle, or candled ice, is a form of rotten ice. It is a beautiful yet dangerous natural phenomenon. Candle ice is formed when a body of water freezes and supercools, or cools below freezing without solidifying. Large ice crystals then form rapidly, and melting begins at the border of individual columnar crystals where the ice contains more impurities. This process separates a thick ice sheet into a packed mass of candle ice.
The presence of wind during crystallization can lead to the formation of horizontal candle sticks, which make the ice appear darker. Candle ice can also form when snowpack and ice are mixed together or when polar ice melts during the spring or summer. Rotten ice may look dark or transparent, similar to new black ice, or it may appear grey and splotchy.
The formation of candle ice increases with time, temperature, and the quantity of water melt runoff. This occurs due to the hexagonal structure of the ice crystals, which can trap minerals such as salt and other contaminants. Melting will begin at the boundaries between crystals due to these trapped contaminants. No matter its thickness, candle ice is dangerous because of its lack of horizontal structure. This means there will be no rim to grab onto for anyone who falls through.
Candle ice makes a distinctive clinking sound when the "'candles'" are broken apart and floating in the water, bumping up against each other. This sound has been likened to a floating chandelier. While candle ice may be aesthetically pleasing, it is important to exercise caution and avoid walking on it or exploring it without a boat, wetsuit, or dry suit and life preserver.

It forms in columns perpendicular to the water's surface
Candle ice, also known as candlestick ice, needle ice, or rotten ice, is a fascinating phenomenon that forms in columns perpendicular to the water's surface. It gets its name from its distinctive shape, resembling upright candles or sticks. This formation occurs when a large sheet of ice begins to melt, and the process is influenced by several factors, including time, temperature, and the quantity of water melt runoff.
The formation of candle ice starts in winter when the body of water freezes. During this process, supercooling occurs, which involves the cooling of water below its freezing point without it solidifying. As a result, large ice crystals form rapidly, and their growth is influenced by various factors. One factor is the presence of wind, which can lead to the formation of horizontal candle sticks, giving the ice a darker appearance.
The unique structure of candle ice is a result of the hexagonal arrangement of ice crystals. These crystals can trap minerals such as salt and other contaminants between them. When ice from a larger surface melts, it does so at the boundaries between the crystals due to the presence of these trapped impurities. This gradual melting separates the thick ice sheet into a packed mass of candle ice. Therefore, the formation of candle ice is influenced by the presence of impurities in the water, in addition to supercooling and relatively still water.
Candle ice typically forms in very cold regions, such as Canada, Alaska, Lakes Michigan and Superior, Japan, and Russia. It is aesthetically pleasing and produces a beautiful clinking sound when disturbed, resembling a floating chandelier. However, it is crucial to exercise caution when encountering candle ice. Despite its attractive appearance, it is dangerous due to its lack of horizontal structure. This means that it cannot support the weight of a person, and there is a risk of falling through. Therefore, it is important to admire candle ice from a safe distance or by boat and to prioritize safety when exploring areas where it is present.

It is caused by the supercooling of water
Candle ice, also known as needle ice, is a form of rotten ice. It is a fascinating phenomenon that forms during the winter when a body of water freezes. The process begins with the supercooling of water, which involves cooling the water below its freezing point without it actually solidifying. This supercooled water then undergoes rapid crystallization, forming large ice crystals that arrange themselves into distinct columns. These columns grow perpendicular to the surface of the water, giving rise to the characteristic "candles" of ice.
The formation of candle ice is influenced by several factors. Firstly, it requires relatively still water, as wind during the crystallization process can disrupt the formation of vertical columns, resulting in horizontal candle sticks instead. Additionally, the presence of impurities in the water plays a role. As spring arrives, melting begins at the borders of individual columnar crystals, and impurities trapped within the ice accelerate this melting. This gradual melting separates the once solid ice sheet into a packed mass of candle ice.
The unique structure of candle ice gives it a distinct appearance and acoustic properties. The individual "candles" clink together when disturbed, creating a beautiful sound akin to a floating chandelier. Despite its aesthetic appeal, candle ice can be extremely dangerous. Unlike solid ice, it lacks a horizontal structure, making it incapable of supporting the weight of a person. As a result, venturing onto candle ice can be hazardous, and it is recommended to explore lakes with candle ice by boat or canoe, or with appropriate cold-weather gear like a wetsuit.
The formation of candle ice is a complex process influenced by various factors, including the supercooling of water, wind, and impurities. It is a testament to the intriguing ways in which nature can transform water into captivating and unusual ice formations. However, it is essential to approach these formations with caution, as their beauty can be deceptive, hiding the dangers that lie beneath their fragile surfaces.

Candle ice is dangerous due to its lack of horizontal structure
Candle ice, also known as needle ice, is a form of rotten ice. It is formed when a body of water freezes, and the crystallization into sticks is due to supercooling, which is the cooling of water below freezing without solidification. Large ice crystals then form very rapidly.
Despite its aesthetically pleasing look, candle ice is dangerous. It is weak and can easily break, even if it is several feet thick. Candle ice has no horizontal structure, meaning that if a person falls through, there will be no rim to grab onto. This makes it impossible to climb out of, and a person could quickly drown.
The danger of candle ice is further increased by its appearance, as it can look strong and stable, luring people onto it. However, the ice will not support a person's weight, and they will fall through. This type of ice is also difficult to spot, as it can be hidden by a layer of white corn ice on its surface, which has a fairly uniform appearance.
The formation of candle ice increases with time, temperature, and the quantity of water melt runoff. This is due to the hexagonal structure of the ice crystals, which allows minerals such as salt and other contaminants to become trapped between the crystals when they form. Melting will begin at these boundaries due to the trapped contaminants.
Candle ice is a significant hazard, and it is essential to be aware of its dangers and take precautions to avoid falling through. It is advised to explore lakes with candle ice by boat or canoe or wear a wetsuit if entering the water.
