I found this at Boyce-Thompson Arboretum in Superior Mountains in Arizona. This is harsh, no water, no live, desert. The arboretum is an oasis of supreme beauty and peace.
As I am desert rat, It was midsummer, midday, when this picture was taken.
Unfortunately I have only this one photo from this angle.
And thanks for going mobile!
