Geocache Description:

Fairbank Fen is a unique and interesting place formed by glaciers thousands of years ago.

 photo SANY2790_zps62ee0c86.jpg A fen is one of the six main types of wetland and one of two types of mire (the other being a bog). It is usually fed by mineral-rich surface water or groundwater.Fens are characterized by their water chemistry, which is neutral or alkaline, with relatively high dissolved mineral levels but few other plant nutrients. They are usually dominated by grasses and sedges, and typically have brown mosses in general. Fens frequently have a high diversity of other plant species including carnivorous plants. They may also occur along large lakes and rivers where seasonal changes in water level maintain wet soils with few woody plants.

Fens can form where a groundwater source rich in minerals is exposed to the surface. Depending on a fen’s location, its foundation was laid either during a glacial period hundreds of thousands of years ago (and since eroded), or during the most recent glacial period — about 10,000 years ago. In either case, the geology provided an ideal setting for the development of a fen.

The most tell tale sign of a fen is a mat of thickly woven moss and cattails that forms across the water surface and may quiver and shake when walked upon. Then imagine that mat becoming so thick it can support trees.

To receive credit for this EarthCache, you will need to apply what you have learned from this EarthCache's description and report your findings to me.
1. The posted coordinates will take you to Fairbank Fen's parking area. Your task is to find the fen and
e-mail me the fen's approximate coordinates.


2. Once you found then fen, tell me if this fen demonstrates the characteristics described above.

I would like to thank
