My recollection is that this field was located on the western side of Grand Loop Rd in Yellowstone NP. I did not record the exact location of the field at the time.
F-8, 1/500 sec, ISO 200, 300 mm Focal Length
I saw the coyote from the road and stopped to try to capture an image. I happened to have the camera zoomed in on the coyote when it leaped into the air to pounce on it's prey. Lucky opportunity!
