Mountain Lion (Felis concolar). This is a full grown male weighing in at about 150 pounds and on a full run when I snapped this photo. I followed the cat from left to right firing as fast as I could. There are actually three frames of this big cat on the move before he took a sharp left hand turn and disappeared over the hill side as you'll see in frame three later. Notice the muscle tone in the front shoulders and it's paws turned inward as it leaps. "Winter Flight'" the second of the three frames won an international award and was subsequently published in a photography album and circulated around the world.
