only Swiss needs to be capitalized because it is a proper adjective. Mountain is not capitalized because it is not the name of a place.
TAKE HOME: NOTE THE "A". IT'S A SWISS MNT. NOT A PARTICULAR MNT.
IF THE SENTENCE WAS "..in the Rocky Mountains" then it's capped.
ALSO NOTICE THE "THE" IS NOT CAPPED BEFORE ROCKY. DON'T CAP THE "THE" WHEN REFERRING TO LOCATIONS.
