Above is a photo taken near the Copper Harbor Lighthouse looking out into Lake Superior. This is the place where the French voyageurs first discovered the rock known as "La Roche Verde." The rock received its "green" color from copper silicate, also known as chrysocolla, which indicated the presence of copper. Not much remains of the "green rock" only what is seen in the photo. Douglas Houghton, Michigan's first state geologist, discovered this vein of copper in 1840 and wrote a report about it which started the first mineral boom in America.Thursday, September 18, 2008

That's an interesting story. Chrysocolla was one of the stones pictured recently in my blog about the stones that we framed. It was one of my favorites.
The blues, the expansiveness of the waters out there and the skies have me wishing I were within this scene to witness it first hand. Wonderful capture my friend.
Donna, I remember those beautiful stones. I also recall how wonderfully creative your project was.
Luis, I wish you were able to see this place too, it has so many similarities to the places you have photographed in New York.
