Does anyone know why western people write name as Elbrus and sometimes as Elbruz?

Actually, here you have 2 completely different toponyms.
This 2 names are mistaken very often (apparently because of the same root).

Mt.Elbrus is on Russian-Georgian border
and Alborz is mountain range in Iran.

Both have many names and some of the names sound almost the same.
Elbruz is how Mt.Elbrus is often pronounced, and you also have Elburz as one of the name of Iranian Alborz.
Elbruz-Elburz...no wonder people make mistakes.

I think that both are habitats of Sempervivums.
