My only thought was if that is what a camera caught at 1/45 of a second... How great the many minutes you spent there must have been! My uncle makes annual trips to Mt. Zion In fact, he's there this week. I'll be going for the first time next year with my D70.
This is straight out of the camera. It was taken in Zion Canyon. You're seeing a very blue winter sky and the reflection of sandstone cliffs. It was pretty cold and you can see ice forming along the edges. Also, some of the streaks are sand in the bottom of the little stream and bare trees in the reflection. No photoshop magic to this one.
