I went to my favorite spot up the hill above all of the commercial areas an did this panorama today. It isn't quite high enough to get more than a 180 degree panorama. I wish I could have included more of the mountains to west. Missing are the Trinity Alps, Shasta Bally, Southfork Mountain and numerous other snow covered peaks to the west.
That's not the curvature of the Earth you're seeing. It is due to the lack of level ground where the tripod was placed.
The mountain just to the left of center in Mt. Shasta (elev. 14,182 ft.). Mt Lassen (elev. 10,457 ft.) is on the far right. Mt Shasta is almost due north in the photograph.
I figured that I'd better get out and shoot this now or I may not get another chance as another storm is forecast to arrive tonight.
BTW - each time in the past that I have taken similar pictures we have ended up having snow in our yard.
