Pronunciation: [zˈastɹuːɡə] (IPA) 
Zastruga is a word that describes a long, narrow groove or furrow formed in snow by wind. The word originates from Russian and is spelled [zuh-STROO-guh] in IPA phonetic transcription. The "z" sounds like the "z" in "zone," the "u" is pronounced like the "oo" in "moon," the "h" is silent, the "s" sounds like the "s" in "sun," the "t" sounds like the "t" in "time," and the "g" is soft and pronounced like the "g" in "gem."
Zastruga is a noun that refers to a form of snow drift or ridge that is formed by the wind and seen on the surface of snow-covered landscapes. Also known as snow dunes, zastrugas are formed due to the interaction of wind and snow on open terrain, typically in cold regions or during winter storms. The term originates from the Russian word "zastruga," meaning "a wave of snow."
Zastrugas are characterized by their elongated ridges or waves that usually run parallel to the prevailing wind direction. They can vary in size and shape, ranging from small undulations to large, imposing dunes. The wind blows the snow particles across the exposed surfaces, depositing the snow on the leeward side of obstacles such as trees, rocks, or buildings. As the wind continues to blow, the trapped snow gathers, forming these distinctive ridges.
These snow formations typically possess sharp edges and steep slopes, making them both visually striking and physically challenging to navigate. Zastrugas can impede travel and outdoor activities, and they may also increase the risk of avalanches in mountainous regions. Yet, they can also have an aesthetic appeal, especially in areas where the winters are harsh and snow-covered landscapes dominate.
Understanding zastrugas is essential for those who engage in activities such as snowmobiling, skiing, or mountaineering, as they can significantly impact safety and overall experience. By acknowledging the presence and characteristics of zastrugas, individuals can better assess the terrain and plan their routes accordingly, ensuring a smoother and safer journey.
The word "zastruga" was derived from the Russian language. It originates from the Russian word "заструга" (zasturga), which means "a furrow" or "a groove". The term is widely used in English and other languages to describe a specific type of snow feature, also known as a snowdrift or a wind-rippled snow formation.
