Post 4

I have never found the great northern diver in the Park lakes. Most of them are inaccessible to him. He might plump down into them, but would hardly be able to get out of them, since, with his small wings and heavy body, a wide expanse of elbow room is required in rising. Now and then one may be seen in the lower Sierra lakes to the northward about Lassens Butte and Shasta, at a height of four thousand to five thousand feet, making the loneliest places lonelier with the wildest of wild cries.

Now take the image above and do some image processing.
