Skulls of wild horses and deer, antlers and countless bones, all crushed into shapelessness, furnished indubitable proof that the carcasses had fallen from a great height.

Most remarkable of all was the skeleton of a cougar lying across that of a horse.

I believed--I could not help but believe that the cougar had fallen with his last victim.
Not many rods beyond the lion den, the rim wall split into towers, crags and pinnacles.

I thought I had found my pipe organ, and began to climb toward a narrow opening in the rim.

But I lost it.
