Snæfellsjökull is a glacier out on the Snæfellsnes peninsula on the west coast of Iceland. It is a much loved mountain in Iceland due to its beautiful volcanic cone lines. It is well visible from Reykjavík from where it appears to float on the ocean.
The glacier has always been linked with mystic powers and was chosen by Jules Verne as the starting point for his Journey to the Center of the Earth. It has also been a center of attention for UFO seekers from around the world. In 1991 UFO enthusiasts and international media flocked around the glacier in anticipation of an alien landing.
Perhaps clouds such as these lenticular altocumulus clouds in the photos below originally triggered these stories.
