Grotto Geyser Details
No other geyser in this basin is more revered for its unique mineral formations than Grotto Geyser. How do you suppose it acquired its unusual shape? Well, as you can see there are lodgepole pine trees growing all around us here. Apparently, well over 1000 years ago, there were trees growing right where Grotto Geyser is now located. Perhaps an earthquake caused a new thermal feature to break out which killed the trees. Over many years, the sinter built up over the dead tree stumps, eventually creating this natural masterpiece. It has been said that Yellowstone is like a living sculpture, always changing. During a typical eruption, Grotto discharges many thousands of gallons of hot water into the Firehole River. The most impressive part of the eruption is the very beginning, when the water may surge to a height of 45 feet. The geyser then quickly settles down to splashes of up to 15 feet. Both the interval between the eruptions and the duration of an eruption can vary significantly. Due to its interesting and ornate mineral formation, and the tremendous discharge of water during an eruption, Grotto is considered to be one of the major geysers in the basin.
