At length, after gaining the upper extreme of our guiding ridge, we found a good place to rest and prepare ourselves to scale the dangerous upper curves of the dome… Thus prepared, we stepped forth afresh, slowly groping our way through tangled lines of crevasses, crossing on snow bridges here and there after cautiously testing them, jumping at narrow places, or crawling around the ends of the largest, bracing well at every point with our alpenstocks and setting our spiked shoes squarely down on the dangerous slopes. It was nerve-trying work, most of it, but we made good speed nevertheless, and by noon all stood together on the utmost summit… We remained on the summit nearly two hours, looking about us at the vast maplike views [that] could hardly be surpassed in sublimity and grandeur; but one feels far from home so high in the sky, so much so that one is inclined to guess that, apart from the acquisition of knowledge and the exhilaration of climbing, more pleasure is to be found at the foot of the mountains than on the frozen tops. Doubly happy, however, is the person to whom lofty mountain-tops are within reach, for the lights that shine there illumine all that lies below.

-John Muir

O the mind, mind has mountains.
