were entirely confined to that locality in the bottom. In the bed
of the river in front, for a space of several hundred yards, they
were very abundant; the effervescing gas rising up and agitating
the water in countless bubbling columns. In the vicinity round about
were numerous springs of an entirely different and equally marked
mineral character. In a rather picturesque spot, about 1,300 yards
below our encampment and immediately on the river bank, is the
most remarkable spring of the place. In an opening on the rock, a
white column of scattered water is thrown up, in form, like a jet
d'eau, to a variable height of about three feet, and, though it is
maintained in a constant supply, its greatest height is attained
only at regular intervals, according to the action of the force
below. It is accompanied by a subterranean noise, which, together
with the motion of the water, makes very much the impression of a
steamboat in motion; and, without knowing that it had been already
previously so called, we gave to it the name of the Steamboat
Spring. The rock through which it is forced is slightly raised in
a convex manner, and gathered at the opening into an urn mouthed
form, and is evidently formed by continued deposition from the
water, and colored bright red by oxide of iron.

"It is a hot spring, and the water has a pungent, disagreeable
metallic taste, leaving a burning effect on the tongue. Within
perhaps two yards of the jet d'eau, is a small hole of about an inch
in diameter, through which, at regular intervals, escapes a blast
of hot air with a light wreath of smoke, accompanied by a regular
noise.

"As they approached the lake, they passed over a country of bold
and striking scenery, and through several 'gates,' as they called
