There was already a huge dig on Marfa from original RC postings- check archives- will save you a lot of time. Oh- there’s a Standard Hotel in Marfa if you didn’t know already.
Um, Charlevoix, MI has a Cemex plant on prime waterfront (but does not appear to be affiliated with the Cemex company of previous Q research). It bugged me then but couldn’t make connections but maybe your post is it.
