I saw this movie approximately late 90s. This movie featured a couple travelling through Snow suddenly a heavy storm came and the woman lost in it, she felt in snow gap after which was covered by snow. she slept and trapped for long time. I’ve been looking for the movie ever since and have had no help. Google can’t help me.
“Snowbound: The Jim and Jennifer Stolpa Story” (1994)?
