You can’t watch Strictly when Lola’s squirrel needs rescuing 😁

Plenty of prehistoric pit and linear features being excavated on a quarry extension near Mold today. Pits filled with heated stone and charcoal suggest cooking activity. Also a possible round hut starting to appear. Much more to be stripped and excavated over the next few months.

Worrying reports of bird flu (avian influenza) are coming in, including an outbreak in Whooper Swans in the Fens. Other waterbirds are also being affected, and cases are rising.

A long time since I’ve been there. Did you see or hear the Choughs ?

For fans of ghost story dramas there is a rare opportunity to see the Screen Two 1995 episode of The Blue Boy set in Scotland on BBC iPlayer www.bbc.co.uk/iplayer/epis...

Screen Two - The Blue Boy

A couple expecting their first baby spend a few days in the Highlands, hoping to make a fresh start to their relationship - only for the past to creep up on the present with devastating results.

Impossible watching Strictly with this attention seeking madam in front of you. She loves teasing the ball then grabs it before you can 😁

Mark Walters @mark-walters.bsky.social · 9d

You can’t beat a bit of sky drama - lovely photo 👍

Mark Walters @mark-walters.bsky.social · 9d

Ahh, yes, Alice Krige was great in that role too 👍

Wondered what the scratching sound in the trees was and looked up to find these two Cormorants watching me from only 10 metres away. Stood there for a few minutes and they seemed quite relaxed and didn’t fly off. Great when these quality close proximity moments happen with nature.

My reconstruction of Allen Smelt Mill (2017) is a good contender for being among my most challenging visualisation projects. It required months of effort, research, and problem-solving with the aid of 3D models. I wrote an article about the experience.... bob-marshall.blogspot.com/2018/01/reco...

Illustrated reconstruction drawing showing a cutaway view of Allendale Smelt Mill in Northumberland, as it might have looked in the 1800s. A central water wheel drives mechanical bellows, which feed a supply of air to the factory's ore hearths. Fumes from the furnaces that burn off sulphur and other impurities in the lead ore are carried away from the factory by a complex network of flues. The Smelting Mill was demolished in the 1950s and 1970s. All that remains are flue openings, the ore hearths, the wheel pit, and the foundations of the roasting furnaces. The flues can be described as long horizontal chimneys, which end at chimneys high up on the moors above Allendale, over two miles away. The flue system here is the best preserved in England.

A reconstruction drawing of Allenheads Mine Yard in Northumberland. Teams of men and boys operated 'jiggers' and 'buddles' to sift and wash the mined minerals to extract every available ounce of lead ore. The process required vast quantities of water. The ore was then taken from here to the smelting mill at Allendale on the backs of small, rugged horses known as Galloways, then deposited into storage bays here called bingsteads, where the material would then await refinement.

This is the only plan drawing we have of Allen Smelt Mill in the 1800s, showing the layout of its buildings and the route of its horizontal flues.

A 3D computer model of 'Brunton Buddles'. This equipment was used for washing the iron ore of unwanted material. The material was loaded through a hopper at the top and then passed on to a canvas belt, where water washed away the unwanted material, leaving lead-rich ore to drop into a large tank for collection.

It could do with a remake, it’s looking very dated now and the acting isn’t great.

And the classic ghostie movie for Halloween tonight is Ghost Story (1981) based on the Peter Straub novel 🎃👻

I often wonder why the two species are drawn to each other in flocks

Mark Walters @mark-walters.bsky.social · 11d

Fieldfare’s are back today for winter with some big flocks flying over or settling in the canalside trees. Always good to welcome our winter visitors. Redwings likely to be back now too.
