Evershot Pit – Geoconservation

The weather gods blessed us today! In the face of a yellow warning of rain, Jonathan, Andy and myself assembled mid-morning in perfect autumnal weather.

Our task was to tidy up Evershot Pit, where the main geological interest is an erosion surface of phosphatized Upper Greensand, overlain by a fossiliferous clay band and Middle and Upper Cenomanian Chalk.

We cleared away fallen branches and some encroaching ivy, then set to exposing the erosion surface by removing the chalk and soil. Our last visit to this site was a couple of years ago, so the accumulation was deep. The task was not made easier by the overnight rain – we made a mental note to visit in the summer next time.

Working away gave us plenty of time for chatting: topics included the fossil fish of the Tibetan plateau, exhumed Triassic landscapes in the Mendips, the probability of two people in a group having the same birthday, and the badgers asleep beneath us in the Foxmould.

Eventually the promised rain arrived. We finished off by erecting a new “DIGS” sign at the site. With a bigger party, we’d be able to extend the exposure to the left.

Many thanks to Ilchester Estates for allowing us access, and to Andy Bradley and Jonathan Stiby for taking part.

Crack Lane – Geoconservation

Conservation at Crack Lane, Langton Matravers on 13th October.

The team was Andy B, Geoff P, Paul and Richard. An excellent morning’s work in the small quarry clearing the face of the quarried area and making good progress to the right hand side which we haven’t achieved before. Clearance of the ground in front of the faces and cutting back buddleia, bramble and hawthorn on the left side have left the site quite clear.

Nature notes: Andy found a number of Nettle leaved bellflower with this one still in flower which was great to see

Kingbarrow Quarry, Portland – Geoconservation

We had a good session this morning at Kingbarrow Quarry in lovely weather. A select band did a great job – Andy, Geoff P, Paul, Richard and Alan.

Alan worked on the access which had become quite overgrown with brambles and blackthorn. The others worked on the fossil forest section.

Unfortunately there is quite a lot of cotoneaster now after the clearance several years ago and Andy did a great job clearing some of that. Some of it was coming through from a neighbouring property.
