Text of sign:

Aurum Geyser

Aurum is Latin for "gold."  The geyser was named for the color of iron oxide deposits lining the vent's rim.  During eruptions, which

occur every 2.5 - 5 hours, water and steam are ejected to heights often exceeding 20 feet.

Fun Facts

Aurum Geyser is a cone-type geyser.

Prior to an earthquake in 1983 Aurum Geyser rarely erupted. 

Eruptions last about a minute.

Geyser Types

All geysers are essentially hot springs that periodically erupt.  Beyond this broad similarity they can be grouped into two

categories: cone geysers (Old Faithful is the most famous of this type) and fountain geysers (like Sawmill or Grand Geysers).

Graphics on the sign

In addition to the text there is a picture of Aurum Geyser and a graphic that shows the difference between fountain and cone 

geysers.
