The call of the wild was too loud to ignore--I hastened my camp making. The sun was going down on a world of splendor. Overhead were brilliantly colored clouds, while deep in the cañon below the early darkness was thickening. From somewhere in the distance came the cry of an animal. Camp was left unfinished; I climbed to a jutting shoulder that overlooked the cañon. From far below came the noise of the river as it chugged and sobbed and roared endlessly between its towering walls. I promised myself I would go down and explore that dark cañon at an early date. Of a sudden there came an indescribable, unearthly sound that echoed and reëchoed among the cliffs. I could not tell the direction from which it came; a sudden chill crept along my spine, my hair prickled and lifted. Then the echoes ceased, the silence that followed was equally terrifying. I bethought me of my unfinished camp. Later I learned that alarming sound was the bugling of a bull elk. It was the mating season. As darkness came on I ate beans and bread by the light of the campfire. The beans came out of a can, so were well cooked; but the bread was my first campfire, culinary concoction. It was a flour and water mixture, plus salt and baking powder, cooked against a hot rock. It was smoked black and cooked so hard it nearly broke my teeth, besides, it had a granite finish from association with the rock oven. But I ate it with boyish relish in spite of its flaws. My imagination expanded as I watched ghostly shadow-figures dance upon the face of the cliff. The shifting flame, the wood smoke, the silent, starry night swelled my heart to pride in my great adventure. I ignored the incident of the animal cry that had sent me scurrying to camp. This first camp was just below timberline, at an altitude of eleven thousand feet or more. I had much to learn about altitude, as well as of winds and weather, woods and mountains. In the mountains the higher one goes the harder the wind blows. In the Rockies, around timberline, gales often reach a velocity of a hundred miles, or more, an hour. Here during the long alpine winters, the wind booms and crashes among the peaks, roars through the passes, and rips through the shattered trees. That first night I lay in camp and listened to its unceasing roar, as it tore along the ridge tops. Occasionally, a gust would scatter my fire. It raged through the spruces like a hurricane, causing me much uneasiness lest one of the trees should come crashing down upon my frail shelter. At last, after dozing before the dying fire, I went inside the tent, crept between my blankets and fell asleep.
