congeliturbation

congeliturbation

[kən‚jel·ə·tər′bā·shən]
(geology)
The churning and stirring of soil as a result of repeated cycles of freezing and thawing; includes frost heaving and surface subsidence during thaws. Also known as cryoturbation; frost churning; frost stirring; geliturbation.

Differences in TDS means are accounted for in part by downwasting of soluble bedrock constituents and unstable substrate surface materials While other factors contribute, biogeographic exposure to post-meridian solar impacts fosters congeliturbation during seasons of freeze-thaw.

Two considerations involving downwasting of solutes are involved: The solubility of the bedrock and; observed factors in PM solar exposure promoting congeliturbation in freeze-thaw periods (Amundsen, 1977).
This drainage is treated separately from the easterly draining tributaries to the Big Wood River (#4) due to the southwesterly PM solar load exposure and less vegetational cover, likely resulting in more dynamic congeliturbation and downwasting processes.
Congeliturbation, notable rock weathering and material downwasting in streams can be assumed, as in watershed #3 above.
