Geyser Basins in Winter.
Of course traveling of this sort is attended with much peril. A man must rely wholly on himself. No wagon or saddle is available if he is injured or sick. Heavy storms may blind him and cause him to lose his way. In short, a snow-shoe trip through the Park is an undertaking which requires a vigorous physique, a determined will, and a good fund of courage. Very few, except those whose duty has required it, have ever made the attempt. But it is the unanimous verdict of those who have, that, glorious as the Park is in summer, it is even more glorious in winter. One can readily understand this to be so. Evergreen forests never appear to better advantage than when laden with snow. Ice formations always enhance the beauty of water-falls. [AX] The rolling open valleys of the Park must be doubly beautiful when robed in drifted snow. It is a pity that this silvery landscape should forever remain excluded from the general view.
