[Need Help w/ Movie Title: B&W Deco Film about a Snow/Ice Queen]

saw a great film some years ago & cannot remember the title for the life of me...

i remember this film only because it was so visually stunning & had these

fantastic arte deco stage designs...

its b&w with sound i believe; probably made between the late 1900's - the early 1930's.

about a group of explorers in some snowy mountains who stumble across and entrance to a hidden civilization... ruled by an ice / snow queen.

she's hundreds of years old... but looks great.

she falls in love w/ one of the men explorers... i think she offers him the foutain of youth or something... be he doesnt love her.

in the end her spell is broken: she turns old & dies. the end

any guesses on what the name of this flix is???

would greatly appreciate any help.

thanks so much!!!
