The Milky Way, viewed from 11,000 feet
While visiting the Colca Canyon in Peru, we stayed at a hotel that was at elevation 11,000 feet--and had an amazing hot springs.
In the thin air, the view of the stars was amazing, especially as you floated in the warm waters of the hot springs late at night. This was the first time I was able to see the Milky Way in all its glory--and to be able to take a photograph of it. (This is a 30-second exposure.)
