The fog crept in as we awaited the appearance of the Sun before sunrise on the day of the Summer Solstice -- June 21, 2010.
Visitors at the sunrise gathering face NE in preparation for seeing the rising Sun. Behind them in the sky and opposite the Sun is the Earth's shadow, that deep grey color just above the hills on the horizon with the pink hue above it. The Earth's shadow is visible to us ~15 minutes before sunrise (in the West) and after sunset (in the East) by being projected onto the Earth's atmosphere.
Visitors stand and watch the stone marking the location where the rising Sun will appear. Notice that the deep grey color of the Earth's shadow in the previous photo has now disappeared (the shadow has set) as the sky lightens and the Sun gets ready to rise.
