Yes, that is how I picture Colorado in front of my inner eye! The sky is a bit weird in 1 and totally blown in 4, which is a pity, you went for a long exposure in 4 to capture the motion of the water, but that did not work well with the sky, and in 1 the clouds look --- funny. But the shadows in the foreground are very ... erm, well, yes ... shadowy. Maybe you can tone-map that one still more?
Too much sky in the third ... so the second cannot but turn out to be my favourite here.
The top one is Lake Isabelle in the Indian Peaks Wilderness west of Boulder.
The middle two are Mills Lake at the beginning of Glacier Gorge, below the west face of Longs Peak in Rocky Mountain National Park.
The bottom one is Alberta Falls, which is about a mile up the Glacier Gorge trail. It's a hugely popular tourist destination unless it's 6:00 AM like in that photo.
