Here's a photo I took from one of my trips up to Loveland Pass, which is near Keystone, Colorado on US 6.
From Wikipedia:
[Loveland Pass] is located on the Continental Divide in the Front Range west of Denver on U.S. Highway 6. The twisty road is considered to be especially treacherous during the winter months... Loveland is the highest mountain pass in Colorado that regularly stays open during a snowy winter season...
This time the sky was loaded with dramatic clouds. Truly an epic scene, but nothing compared to how it is during a bad winter storm. This will always be a regular destination for me.
