I was standing on the dock in Havasu City, California. The second strip of water in the photo is actually 3 miles across. That is Lake Havasu City, Arizona at the base of the mountain. The sun was setting behind me.
Thanks Pete, Andrea and Jeff.
Jeff, Yes, I love photographing lone trees.
Andrea. The dividing line between California and Arizona (here at Lake Havasu City) is in the river. It is a 75 mile drive over to this dock from LHC because it is desert and there are not many bridges across the river.
