Giant Geyser Cone

GIANT GEYSER CONE, YELLOWSTONE NATIONAL PARK

Text on the back:
The flint like rock of which this cone is composed has been deposited by the hot water thrown out during eruptions of the Giant Geyser over a great period of time. No change in its appearance has been noted since a pencil sketch of it was made in 1870.
