What is the difference between bogs and fens?

Why do bodies not decompose in peat bogs?
As new peat replaces the old peat, the older material underneath rots and releases humic acid, also known as bog acid. The bog acids, with pH levels similar to vinegar, conserve the human bodies in the same way as fruit is preserved by pickling. This allows bog acids to saturate the tissues before decay can begin.
Can you walk on a bog?
That partially decayed plant material is called peat, so a peat bog is a mix of water and land. Stepping on peat it feels spongy and squishy. Therefore, it is possible to walk through a bog but you risk getting stuck up to your knees. However, it’s possible to use bog shoes, which make getting around much easier!
Why are bogs so dangerous?
These may run beside streams or even over them if the ground below is honeycombed with watercourses that have eroded the peat but are not yet visible on the surface. These undercut holes can be very dangerous when covered by snow because you can fall in and break a leg or get swept away by rushing water.
How deep is a bog?
The depth of the peat can range from two or three meters (about six to ten feet) up to about five meters (around 16 feet). Rainwater tends to flow through the dryer looking top layer of the blanket bog, which floats like a carpet on top of the waterlogged moss beneath.
