  1. Pretty ugly on the landscape, but stunning when seen by shaded lidar. The projections at the periphery are slate waste tips.

    Alexandra slate quarry, Moel Tryfan, north Wales.

  3. If you like your adits and industrial archaeology, here's a free, very visual write-up for you about the mile-long Penrhyn quarry drainage adit, built 1847-1849, possibly involving some Latter Day Saint drivers, though we failed to find definitive evidence so far.

  5. 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.

  7. This afternoon's completion of documenting work I started back in 2022. This is 500m inside a mountain of alternating slate beds and grits. The dip of the slate beds is remarkably clear here. Time travel, back to 1847 when this drainage adit was started, and simultaneously 500 million years back to when this was all deep sea sediment.

  11. I've seen many manganese quarries and mines, but never one quite like this. Repeated piles of stones, apparently spoil heaps but they are quite odd. The narrow vein must have been chased on the surface.

    The landscape is almost all sandstone and mudstone, about half a billion years old.

  12. I'm presently working on research, on foot and on paper, into a slate quarry tramway tunnel in north Wales.

    Let's see if anyone out there with an interest in railways, perhaps even this one, can add to my very draft-stage document, which still contains trains of thought for later resolution (or not!) Obviously, all the material is my own copyright, unless otherwise stated.

    The more that take a look, maybe the more we may learn.

  13. Very pleased that a simple magnetic compass and measuring wheel (lit by torch!) suvey of an old slate quarry tramway tunnel (yellow) turned out in pretty-much perfect alignment with the portals at each end. I didn't have knowledge of the 1889 map until after the survey.

  14. Surveying these past days has taken me to a much-visited but little-studied tramway tunnel in a north Wales quarry site.

    Built sometime after 1828, it may originally have been an open cut, but was then covered over to accommodate slate tipping overhead.

    The tip has sat as a vast mass over this rudimentary archwork for over a century. It's still bearing up, but there are clear signs of pretty imminent failure beneath the apex of the tip.

  16. The mighty Dorothea slate quarry Cornish beam engine pump, north Wales.

    This dewatered the increasingly-deep quarry pit, which eventually reached about 108m below local surface level.

    The quarry ceased operation in 1970 and quickly flooded thereafter.

  26. On the edge

    These are abandoned quarries in the Zhytomyr region of Ukraine, June 2022. Outdated methods of mineral mining caused the water pollution and discolouration.
