A rainbow or snowbow

This rainbow appeared in front of us as we traveled in  some clouds of snow and rain at Rocky Mountain National Park. As we came around the curve in the road, it was right there where the sun peeked through!  You can see the road below where we were heading...lots of S curves to this road.  

The "sticks" along the road are 10 feet tall..they are markers that show where the road is when it snows!    I do know the park closes the road in October and does not open it again until May!
