Another stiff pull up the slope brought me under the rim wall, and there I groaned, because the wall was smooth and shiny, without a break. I plodded slowly along the base, with my rifle ready. Cougar tracks were so numerous I got tired of looking at them, but I did not forget that I might meet a tawny fellow or two among those narrow passes of shattered rock, and under the thick, dark pinyons. Going on in this way, I ran point-blank into a pile of bleached bones before a cave. I had stumbled on the lair of a lion and from the looks of it one like that of Old Tom. I flinched twice before I threw a stone into the dark-mouthed cave. What impressed me as soon as I found I was in no danger of being pawed and clawed round the gloomy spot, was the fact of the bones being there. How did they come on a slope where a man could hardly walk? Only one answer seemed feasible. The lion had made his kill one thousand feet above, had pulled his quarry to the rim and pushed it over. In view of the theory that he might have had to drag his victim from the forest, and that very seldom two lions worked together, the fact of the location of the bones as startling. 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. The extraordinarily cut-up condition of the wall made holding to one direction impossible. Soon I realized I was lost in a labyrinth. I tried to find my way down again, but the best I could do was to reach the verge of a cliff, from which I could see the cañon. Then I knew where I was, yet I did not know, so I plodded wearily back. Many a blind cleft did I ascend in the maze of crags. I could hardly crawl along, still I kept at it, for the place was conducive to dire thoughts. A tower of Babel menaced me with tons of loose shale. A tower that leaned more frightfully than the Tower of Pisa threatened to build my tomb. Many a lighthouse-shaped crag sent down little scattering rocks in ominous notice. After toiling in and out of passageways under the shadows of these strangely formed cliffs, and coming again and again to the same point, a blind pocket, I grew desperate. I named the baffling place Deception Pass, and then ran down a slide. I knew if I could keep my feet I could beat the avalanche. More by good luck than management I outran the roaring stones and landed safely. Then rounding the cliff below, I found myself on a narrow ledge, with a wall to my left, and to the right the tips of pinyon trees level with my feet.
