Magnesian Conglomerate
The Magnesian Conglomerate is a geological formation in Clifton, Bristol in England (originally Avon). It dates back to the Rhaetian stage of the Late Triassic.[1][2] This formation was first studied in 1836 by Henry Riley and Samuel Stutchbury.[3]

gollark: My browser's element inspector *says* you have some empty `<p>` tags, so it looks like you just managed to mess it up and the browser displays it in a vaguely coherent-looking way.
gollark: You seem to have some random unclosed `<b>` tags... in the middle of other stuff...
gollark: This... also isn't really spec compliant and should probably not parse.
gollark: Also, `<br>`s everywhere for layout are kind of bad, you can do margins/padding in CSS.
gollark: Although... *why* do you have empty `<p></p>` tags and why does this use `<b>` everywhere?
