“The springs cover an extent of a number of acres, but the principal ones are in a very narrow canyon with very steep sides. They break out on the bottom… There are hundreds of springs—of boiling water—boiling, hissing, roaring. The whole ground is scorched and seared, strewn with slag and cinders, or with sulphur and various salts that have either come up in the steam or have been crystallized from the waters. “
