Frozen air bubbles in the lake
Abraham Lake is an artificial body of water on the North Saskatchewan River in western Alberta, Canada. The lake was created in 1972 after the construction of the Bighorn Dam and named after Silas Abraham, a 19th-century resident of the Saskatchewan River Valley. In this lake, you can observe a rare phenomenon – air bubbles that freeze right under the surface of the water. They are often called ice bubbles or frozen bubbles.
Plants at the bottom of the lake release methane, which freezes when it approaches the colder surface of the lake.
And in winter, when the weather gets colder and colder, these air bubbles begin to accumulate under the surface of the lake.
When a frozen lake is not covered with snow, walking on its surface, under which such bubbles have accumulated, is very unusual and interesting.
Even though the thickness of the ice is about 20-22 cm, walking on the surface of the lake is still scary.
You see cracks running in different directions, as well as the darkness of the lake below.
Well, don't forget about the crunch under your feet every time you take a step.
