The hills surrounding the upper geyser basin are remnants of acidic lava rock from the Quaternary (Pleistocene).

Glacier deposits ( moraines ) from the last ice age created storage areas for water under the geyser basin. Geysers are only possible thanks to this storage facility.

Signs of severe erosion are omnipresent in the upper geyser basin - from drainage channels cut into the sinter to the drainage of the Firehole River. Mountains form south of Old Faithful. There the Rocky Mountains reach a height of 2518 m and divide the country into two water catchment areas .
