Translation of highlands in German

I am trying to learn Spanish because Spanish is becoming more and more important in the USA because of immigrants. Especially here in Texas. I used to live in Nevada for many years. Boring place, gotta tell ya.
In the end of the day we went to visit the Vietnam war museum. It is actually called the American war museum. It gives the Western visitors a different point of view of the events forty years ago.
The American girls came with T-shirt and sandals, not exactly the right equipment for a trip 5000 meter over sea level and minus 10 degrees outside temperature during the day. Anyway, the landscape was fantastic.
