Beaded stream, Yamal Peninsula, Siberia, Russia.

October 27, 2014 in post by Fortier.D

Beaded stream is a type of periglacial stream which is characterized by its seesaw pattern and numerous ‘beads’. Beaded streams evolve over hundreds of years from the degradation of the upper portion of ice wedges due to water flow in ice wedge trough. The so-called beads are located at the junction of ice wedges. Beaded stream are expected to become more frequent in response to climate warming.
