This website (

"DEPRESSION GEYSER lies in a depressed area of ground on Geyser Hill, giving it the name. Some years depression has been quite regular at about 3 hour intervals, but other years it can be irregular and/or have many hours between eruptions. The eruptions can have many bursts or just one. During an eruption, the water level drops to at least half way down the part of the crater you can see from the boardwalk. At that point it may have a ‘washing machine cycle’ where the water sloshes around and bursts can come from a back vent.
WATCH FOR: During the intervals, the water level rises and falls cyclically (often every 20 minutes, but it can be longer or shorter), and the water level rises in the crater with each cycle until reaching overflow. Then the water will continue to cycle to fill the overflow channel and then drop to just below overflow. Right before an eruption, the water will boil and flood the platform or depressed area. As soon as enough water weight has been shed, the bursts will begin."
and this website (

"Temperature 200°F Interval 3.5-5.5 hours. Duration 2-3 minutes. Height 8-10 feet. Prior to 1959 Depression Geyser was an unnamed spring and seldom erupted. It received its name because of the depressed appearance of the old sinter crater. The 1959 earthquake set this geyser into action and subsequent earthquakes have caused changes in its activity. An eruption is characterized by a strong overflow and a pulsating, splash-type eruption. Between eruptions the crater gradually fills with water colored a deep green. No underground connections are known to exist with other springs."
