Stream bog in Epping Forest51.680356,0.076872

Might belong under "Forest & Wilderness" rather than "Bogs or Swamps", but according to a friend this is a stream bog.

Coordinates are an estimate, but the area is well worth exploring. If you head south from the path next to Ambresbury Banks, you will almost certainly encounter mud, especially in wet weather. I know at least one spot you will sink up to your waist in, if not deeper - looks like a dried-up stream bed with a tree fallen over it, and the tree comes in handy when trying to get out again!

Last time I was looking for this, I was heading towards the tree and suddenly sank into deep mud past my knees in a spot that looked perfectly safe.
