Iron Fens



Came across this sign for Iron Fens along Geneva Creek, near South Park in Colorado. Not having a clue as to what Iron Fens were, I took photos anyway. Turns out

Iron fens area a phenomenon unique to Colorado. There are eight iron fens documented in Colorado, and no other known occurrences in the world.

A fen is an area of peat-forming wetlands that receives nutrients usually from upslope mineral soils and groundwater movement. Fens differ from bogs in that bogs are acidic, not alkaline, and bogs are fed by rain water, while Fens are fed by ground water.
