John Muir on Mt. Ritter:
After scanning its face again and again, I began to scale it, picking my holds With intense caution. About half-way To the top, I was suddenly brought to A dead stop, with arms outspread Clinging close to the face of the rock Unable to move hand or foot Either up or down. My doom Appeared fixed. I MUST fall. There would be a moment of Bewilderment, and then, A lifeless rumble down the cliff To the glacier below. My mind seemed to fill with a Stifling smoke. This terrible eclipse Lasted only a moment, when life blazed Forth again with preternatural clearness. I seemed suddenly to become possessed Of a new sense. My trembling muscles Became firm again, every rift and flaw in The rock was seen as through a microscope, My limbs moved with a positiveness and precision With which I seemed to have Nothing at all to do.
