Mucky ground' is a term used to describe a type of soil that is very wet and muddy. It is often found in low-lying areas where there is a lot of rainfall or near bodies of water. The term 'MIRE' is used to describe this type of ground as it is made up of a mix of clay, silt, and organic matter that has been compacted together. Mucky ground can be difficult to walk on or drive through due to its slippery nature and the fact that it can quickly become deep and muddy.
