Awesome shot and a great job on the pano. I haven't been back out west in about 11 years but it sure makes me miss the mountains.
One hint / tip. When you know you are going to shoot a pano series, get your meter reading, then put your camera in manual, set to your meter readings and don't change from frame to frame. this will help keep color / temperature balance, even as the clouds move across your lighting.
Excellent job.
