Sierra Blanca
I was rambling alone on snowshoes, doing some winter observations in the alpine heights of the Sangre de Cristo range. It was miles to the nearest house. There was but little snow upon the mountains, and, for winter, the day was warm. I was thirsty, and a spring which burst forth among the fragments of petrified wood was more inviting than the water-bottle in my pocket. The water was cool and clear, tasteless and, to all appearances, pure.
As I rose from drinking, a deadly, all-gone feeling overcame me. After a few seconds of this, a violent and prolonged nausea came on. Evidently I had discovered a mineral spring! Perhaps it was arsenic, perhaps some other poison. Poison of some kind it must have been, and poisonous mineral springs are not unknown.
The sickness was very like seasickness, with a severe internal pain and a mental stimulus added. After a few minutes I partly recovered from these effects and set off sadly for the nearest house of which I had heard. This was eight or ten miles distant and I hoped to find it through the guidance of a crude map which a prospector had prepared for me. I had not before explored this mountainous section.
SIERRA BLANCA IN WINTER
The gulches and ridges which descended the slope at right angles to my course gave me a rough sea which kept me stirred up. I advanced in tottering installments; a slow, short advance would be made on wobbly legs, then a heave-to, as pay for the advance gained.
