I found this 2019 picture of Spud, plus a wonderful slab of iron-stained "landscape" sandstone which I bought from a stone supplier. It was trade named "Modac", which seems to be a generic name for lots of sandstones from India, but I neeeed to track down the exact source. 😍 #Sandstone #BuildingStone #Dog

The red stone among the usual buff sandstone is a mica-porphyrite rock, probably from Harden Quarry about 8 miles away into the Cheviots. Known as 'Harden Red' its been used in the Mall and to give colour to motorway hard shoulders. I've only found a little here where this tree fell, some of it surfaced in the roots, probably used to build the road here. Its too angular, only good as infill for me. #geology #BuildingStone #Northumberland

Finished the repair of my garden wall. I added some new dimension sawn stone that I had lying around. In there now is, in addition to the locally quarried soft grey silty sandstone, sandstone from near Hexham and a coarser Grit from Crosland Hill, above Huddersfield. It's a well travelled wall. #Northumberland #Yorkshire #BuildingStone
