Scottish meteorite! Pals at Glasgow Uni have identified area between Loch Treig and Loch Ericht as the likely fall zone. A huge area of mountainous ground. Scotland must be one of the worst places to recover meteorite falls - lots of vegetation, especially bogs, big areas with no population, wet weather etc. The last one recovered was in 1917, although dozens of sizable ones must have fallen since. #NaeChance #Meteorite #Scotland
Very pleased to have spotted this anonymous lifting stone at the wonderful Glengarry community hall/cafe/ heritage centre. It turns out to be the legendary 132kg Invergarry stone. The roundness and weight means it's immovable by mortals (eg me πŸ˜ƒ), although heroic videos are available online. #LiftingStones #Scotland image
#MinCup25 Two fine minerals facing off in today's bout: the exotic, chemically and structurally intriguing perovskite vs the ubiquitous chameleon that is calcite. @npub1ssgr...swjk/115143274766404499" target="_blank" rel="noopener">https://mastodon.scot/deck/NOSTR_0/115143274766404499 This year I'm going for #calcite Among other things, it makes for some completely bonkers, unusably fragile gemstones. like this one, which turns a ray of light entering the stone into 8 rays leaving the stone.

Yesterday a friend showed me this beautiful potato which was owned by her great grandfather, who had been a farmer in East Lothian. The miracle potato had survived, and been passed down the generations. πŸ€©πŸ˜‹ See Alt text for the #SecretOfThePotato #BuntΓ ta #Potato #Tattie image
Here's a wee thread of some favourite highlights from the Industrial/Horticultural tent at this year's Bunessan Show on Friday: the fiercely contested "bowl containing approx. 1l of homemade compost" category: 🧡 /1 #BunessanShow #Mull #Compost
Round pebbles are surprisingly rare, as @Bob Downie has noted... Here's a large and very spherical pebble (strictly a cobble πŸ€“ ) which I found a few years ago at Kilfinichen Bay on Mull. Not quite my roundest natural stone, but it gets bonus points for large size I think. #Geology #RoundestPebble image
