Throwing a Rock at the Mountains - Grand Teton National Park, originally uploaded by Carl's Photography.
After leaving Yellowstone and driving south we encountered Jackson Lake with the Teton Mountain range in the distance. We stopped at the shore and Brent threw a rock over the lake at the mountains. I caught him in mid throw and in large view you can see the rock over the water..
