A good friend of mine, Sciguy315 responded to my mini-meme about trees that have stood out in our memories of field work and trips in geological settings. Since it was mentioned in the comments, I hope it is ok to give the picture a slightly wider audience. I especially loved his choice, as I was with him when this picture was taken. We were exploring a trail in Canyon DeChelly at the moment of moonrise, and we all were experimenting with open shutters. I was so wrapped up with photographing the ruins that I missed the tree. He produced a great many wonderful scenes of our summer adventure, which can be seen here.
Some other nice photos have popped up here, here and here. Thanks for the great pictures, everyone!
