This is a circular walk
This time of year's short days favour walk areas close to Bristol, hence the choice of East Mendip, an area we do not much visit.
It is an extremely varied area geologically, with the route crossing bedrocks which range from the oldest in Somerset, at 415 million years arising from a large volcano, to those of a mere 200 million years of the Jurassic era. In between are marine sandstones, the familiar Mendip limestone, coal bearing rocks and an infilled desert wadi. All this rock formation was interspersed with successive periods of deposition, folding and erosion. Not all of this is particularly apparent from surface observation, but it is what the geological maps show.
Features from more recent times include an iron age fort at 2500 to 3000 years, whose builders knew a good bit of real estate when they saw it as, weather permitting, there will be fine views of the Somerset levels. There will be two Roman roads, part of the disused Somerset and Dorset railway (a torch might be handy but by no means essential for a short length of tunnel), an area containing former coal mines, and a pub of unknown vintage in Binegar.
