Yeah. It looked American for some reason. I have seen cloud fronts move through the sky like that. It's not like the Morning Glory. Clouds like that one there usually move really quickly and precede a torrential downpour in my experience. Still pretty bizarre when you see them. The Morning Glory is more mysterious, not fully understood and much, much bigger (a huge and single smooth line of 1000km). It's used a lot by hang gliders and other similar fliers which is insane in itself because the water under it is some of the most shark and crock infested waters in the world (those guys are almost as stupid as flerfs I think sometimes ;) ).
No! Send it and tell them it's the mighty Ice Wall. It's a pic from a secret Deep State military city, build to monitor the wall, so "they" never come to our side.
Good to know there's shopping at the Edge.
