Above are the Lower Falls of the Yellowstone River, taken with a 1.3 second exposure to give the water that lovely silky texture.This is the canyon that those falls are emptying into. At the lower right corner of the picture you can see a tall tower with some darker rock.
On top of that was this osprey's nest with three young birds.Above and below, the astonishing Mammoth Hot Springs. This landscape looks truly alien. Just a small sample of what I took today. More will come later.
