I found these little blue flowers growing on a mountaintop in northern Nevada at nearly ten thousand feet above sea level.  In the desert, it's rare to find anything blooming in June and no one knew what they were, but at ten thousand feet, I'm guessing they were some sort of alien flower planted by E.T. and his friends because there's no other explanation for something that can live with as little oxygen as there is up there.  In a related story: remind me never to go hiking at ten thousand feet without an O2 tank.
