I think, without being absolutely sure, that this is the east side of Ingólfsfjall in southern Iceland, seen from the road from Geysir to Þingvellir. The photos making up this panorama were definitely taken from that road, whatever the mountain may be called.
This was one of my first attempts to use the Canon PhotoStitch software to stitch together photos taken on a DSLR rather than a compact camera. It was a bit tricky, as you have to put in the focal length of the lens and are only given a limited number of choices. I used three photos and you can clearly see one stitch and the other of you look closely. I'll probably fix them in Photoshop when I have the time and inclination. Until then, enjoy the clouds and the landscape:
