Coming over Black Butte Summit I saw a bank of clouds forming around the base of the mountain, and worried that the long drive might have been in vain, but once I got past Weed, to the north side of Shasta, it cleared out nicely.
Though I thought I'd have only about a half an hour of light when I got there, I managed to get several nice images of the mountain from the north before the sun went down.

The last photo is a stitch of 10 images taken with a 600mm lens, and shows incredible detail. The original image is 16,400x5120 pixels!
All in all, a great - if short - day of shooting. The biggest bonus was seeing the sun!
