“ To non-scientific readers, Gesner will be best known for his love of mountains (below the snow-line) and for his many excursions among them, undertaken partly as a botanist, but also for the sake of mere exercise and enjoyment of the beauties of nature. ”

“ In 1555 Gesner issued his narrative (Descriptio Montis Fracti sive Montis Pilati) of his excursion to the Gnepfstein (6299 ft.) , the lowest point in the Pilatus chain, and therein explains at length how each of the senses of man is refreshed in the course of a mountain excursion.
