Superior Mirage

The forecast was mega-inverted, but for clear skies; great for a hike somewhere and maybe even a flight back down. I packed my wing in the car but in the end I just had a nice walk along the Campsies, a line of lowish (500 m or so) hills to the north of Glasgow. It was frosty down in the valleys, but up on the tops it was glorious sunshine and shirt sleeve weather, with great views of snowy mountains in every direction. But then I realized I was seeing a chain of high, snowy mountains out to the SE. Strange, there are no mountains there! To say the least, it was unsettling; I didn't have a camera, but I took some grainy pics on my phone.
Over in that direction, the only hills are the Pentlands, some low hills just SW of Edinburgh. That's what I was seeing and the image was distorted by the huge inversion. As I walked along the hills got even bigger until they looked like the front range of the Rockies in Colorado. When I got home I checked on the internet; I saw a superior mirage, which is quite unusual.
