Partially decomposed vegetable matter - in the absence of bacteria and oxygen, such organic material survives. It will preserve some materials that are in it, as it is usually acidic. Skin can be preserved in peat bogs - acting like a natural tannery, but bone will be dissolved. Pollen can be preserved in stratified layers with a peat bog, making them sites for taking cores for pollen analysis. Peat can be used on gardens or as a fuel on a fire. A peat cutting is where such peat is taken from. The peat is then moved, sometimes by a sledge in the uplands, to a peat stand where (like a stack stand) it is allowed to dry before use.
