Sulphur Mountain Formation[edit]

5x expanded by Georgialh (talk). Self-nominated at 18:55, 20 February 2018 (UTC).

Length and history verified. Copyvio check turns up no problems. Reference verified for main hook; taking it on good faith for ALT1, which I like more. I have also edited both hooks so a reader knows where they are. Daniel Case (talk) 21:21, 13 March 2018 (UTC)
