    I’m sorry to be persnickety (again), but shouldn’t “Gottlob” be translated as “Praise God”, rather than “Thank God”?
    At least the mineral isn’t named after the notorious football commentator Gerd Gottlob. 🙂

    This is funny! I asked myself, whether “Praise God” or “Thank God” would be the best translation. I think, it depends on the word class. Of course, Gottlob is a name of that hill and a noun, but you can also take it as “gottlob ist dort ein Berg, um Gott lobzupreisen”. And because the “preisen”, i.e. praise in English, is missing, I interpreted it as an adverbial expression. 🙂

    Indeed – I did not think of the use of the adverb “Gottlob” as an old-fashioned version of “Thank God”. Gottlob you’ve clarified that! 😉
