Is it an island in the midst of a calm sea at sunset? Nope!
Light deceives the eye, and at dusk, this Arizona copper mine looks almost ethereal, doesn't it?
Look closely at the bottom edge of the photo, and you'll see buildings at the base of the copper mine. The tailings wrap around the hill that stands above the horizon.
I captured this photo just after sunset this evening, standing on Sentinel Hill among rocks decorated with petroglyphs 1,000 years old. Sentinel Hill is part of Saguaro National Park West. This view is to the north.
Doesn't this make you want to visit Arizona? Call me.
