THE WASHBURN YELLOWSTONE EXPEDITION.
NO. II.
Page 10
All around the geysers the ground was covered with incrustations and
subsilica; and immediately about the vent of most of them the incrustations
rose several feet above the surrounding level, assuming grotesque and
fanciful shapes.
"Old Faithful" was the first geyser we saw throwing up a column of
water. It was named on account of its almost constant action. It did not
intermit for more than an hour at any time during our stay. It had a vent
five feet by three, and projected a solid column of water to a height of
eighty or ninety feet. All around it were found pebbles and small stones,
which, when broken open, proved to be simply pieces of wood, thoroughly
incrusted, and perfectly hard and smooth on the outside, having the
appearance of an ordinary stone.
About the crater of "The Castle" was the largest cone, or mass of
incrustations, in the basin. For a hundred yards around, the ground,
flooded with subsilica, of glittering whiteness, sloped gradually up to the
cone, which itself rose thirty feet, nearly perpendicular. It was quite
rugged and efflorescent, and on its outer sides had a number of benches,
sufficiently wide for a man to stand upon. These enabled us to climb up and
look into its crater, which was irregular in shape, and about seven feet,
the longest way, by five feet, the shortest. The outside of the mound was
nearly round, and not less than thirty feet through at its base. We called
it "The Castle," on account of its size and commanding appearance. It was
in action a short time on the morning after our arrival, but only threw
water about thirty feet high. The water did not retain the shape of a
column, like that thrown out by "Old Faithful," but rather splashed up and
slopped over. This geyser did not appear to be doing its best, but only
spouted a little in a patronizing way, thinking to surprise us novices
sufficiently without any undue exertion on its part.
The mound around "The Giant" was about twelve feet high, and had a piece
knocked out of one side of it, so that we could look into the crater, which
was shaped like a hollow cylinder, and six feet in diameter. "The Giant"
discharged a column of water, of the same size as its crater, to a height of
a hundred feet. It played as if through an immense hose. We thought it
deserved to be called "The Giant," as it threw out more water than any other
geyser which we saw in operation. Its cone was also large, and the water
was very hot; as in fact, was the case with the water of all the geysers.
The day of our arrival, it was in nearly constant action for about three
hours, after which we did not see it again discharge.
"The Grotto" has two craters, connected on the surface by the
incrustations which surround them. We did not ascertain whether there was
any subterranean connection between them. We did not observe both craters
discharge at the same time, but one began when the other ceased. Neither
was in action for more than an hour. A solid stream was thrown up more than
sixty feet; that from the larger crater being about five feet in diameter,
and that from the smaller one not more than three feet. The larger mound of
incrustations was about ten feet high, and twenty feet through at the base.
There were several holes in it large enough for a man to crawl through,
which some of the party did, when the geyser was not in action. The smaller
mound was not more than five feet high, and shaped like a hay-cock, with a
portion of the top knocked off. the two mounds were about twenty feet
apart, and connected by a ridge, or neck of incrustations, two feet high.
"The Grotto" was about a hundred yards from the river. A quarter of a mile
farther back, and just at the edge of the timber, we found a mound in the
shape of a cone. At the vertex was a small opening, not more than a foot in
diameter. This geyser did not appear to have discharged for some time. The
ground was quite dry all around, and a number of incrusted pine twigs,
leaves, and cones were found, which retained their shape perfectly, but were
hard, smooth, and white as alabaster. At that point, much ballast was
obtained for the pack animals.
