Were you previously aware of the term "Kjølen" to refer to the (Northern) Scandinavian mountain range? And if so, when you wrote
> I have not heard of any Kjolen Mountains,
were you really distinguishing between Kjolen and Kjølen? Are you a native Norwegian speaker?
I understand that ø is a "distinct" letter in Norwegian, but to my uneducated eyes/ears it sounds similarly baffling to a French speaker not recognizing the "Pyrenees" because they're used to "Pyrénées".
