What was the eulogy poem about an eagle flying over a mountain top on either West Wing Crossing Jordan or Without a Trace?

As I stand on the mountaintop, as the great bird approaches. She is small in my sight, but grows larger on approach until I am blessed with the full sight of her graceful wings, proud countenance and good company. All too quickly, she grows small again on the horizon and disappears from view. And I call out, "Look, there. She's gone." But there are other mountaintops beyond me. And at the precise moment when I note the great bird's departure form my view, I know there are new eyes taking up the sight of her. And fresh voices calling out, "Here she comes!" this is the poem on that episode,

a man named Henry van dyke did the orignal poem
