Welsh-Polish grandchild of forced labour survivors of the Nazi regime. The rule of law: all else follows from there. Former microbiologist, now wandering over and inside the mountains, capturing and writing about north Wales' heritage. Fellow, Royal Astronomical Society. I also fly and motorcycle.

Mirror-like reflections of the sky on the way to RAF Valley this morning.

A cupboard door, made from earlier panels, as revealed by bevelled edges that cut into the ship at far right.

The ship graffiti is probably mid 18th - late 19th century, based on similar graffiti cut onto tombstones here and elsewhere on Anglesey. They are generally physical prayers for good fortune at sea; deaths at sea were exceptionally common then.

Unique within a church on Anglesey, so far as I know, but common enough outside.

Pretty impressive low pressure out there today. Heavy squally showers running through north Wales at the moment.

Once upon a time, I was a microbiologist. So I was quite excited to find this collection of streamers amongst ochre, probably bacterial exopolymer with a slightly less blue colour in real life than this shot (due to lighting constraints). It's within an 1849-cut mile-long drainage adit for a slate quarry.

Anybody know of a good UK-based lab that could do some metagenomic analysis and without breaking the bank (I'm just a poor volunteer!)

The drill holes and the timber plugs in this underground drainage adit are clearly original mid-19th century. The nails still in some of them? Probably original, but I'm not sure.

I'm assuming, as these plug are consistently in the centre of the adit roof, that they were for keeping the adit on the correct heading.

If you know better, or can confirm my thoughts, please let me know, especially if you know what you're talking about!

Context: north Wales slate area.

Nice to go underground for a couple of hours to see my old 1862 friend, No. 2 hydraulic pump at a north Wales slate quarry. This kept levels 120 feet below this floor free of flooding and operated for a century with little maintenance. Its fuel was the original, free renewable: a head of water.
