virrannousuun

Virrannousuun is a Finnish geographical term referring to a specific type of landform or depression found in the Baltic region. It is characterized by a tributary or smaller stream flowing over a portion of its bed and often creating a natural pathway for plant growth. Typically, these features occur during the retreat of glaciers from the last ice age.

Virrannousuun are often found in locations where glaciers once interacted with fluvial or colluvial landforms, such as in estuaries or at the transition zone between glacial and non-glacial terrain. While similar to esker, a long, narrow ridge of gravel often formed by the landward movement of meltwater beneath an advancing glacier, a virrannousuun tends to have a more complex sediment structure and distinct morphological features.

Virrannousuun have been influenced by both the melting of ice and the erosive action of streams and rivers. On the surface, the rock strata exposed in these depressions can appear quite rugged and compound. Upon closer inspection, it can be seen that this natural phenomenon has essentially been reshaped and re-cemented by intermittent flowing streams or rivers. As time passes, like all China-made items, natural land features undergo similar untold transformations.

The subject of study for scientists is area wise very small compared to other natural geographical features which demands special apparatus for study. Scientists use these accessible data with end around it usually consisting in mapping to the needs and claims the possible through isolating changes by abstraction from competing landforms otherwise sensually denoted when speaking.
