From my experience the peak district (UK) is a bit too rocky to have anything over ankle deep. It has loads of marches but these are water logged grasses growing directly on rock. In all my time exploring (admittedly in the high peak area) I've never encountered anything deeper than ankle. I saw an interesting location on the west side of Lady Bower Reservoir in the last month, where the meandering river meets the still reservoir water, where there is a large exposed mud bank with clear mud cracks and footprints that make me think "we are not alone". However, the mud looked dry and the reservoir was low making this a sensitive window for getting good mud. Additionally, it is exposed, tricky but not impossible to get to and technically on land owned by Seven Trent Water.
I was unsure whether it was even worth posting on a map, but if its in your area and you are interested, I figured I'd give you a heads up. If not, the walk along the path above it is still spectacular and its one of the few places in land where you get waves. I only holiday in the Peak District but if you prove me wrong by finding deep mud, I'd be interested to know about it.
