I understand bursts of impulsive curiosity but I’m thinking if you bring a digital thermometer on a trip to Yellowstone, this kind of illegal behavior must have been premeditated. Watch as a tourist visiting Minute Geyser hangs a thermometer taped to a stick over fragile geothermic feature. Ironically Minute Geyser which ironically features an informational sign with the phrase “Choked By Ignorance” as early visitors the park to the area used to toss coins and whatever else they could find into the geyser while they were waiting for stagecoaches. Over time, this vandalism plugged the geyser’s plumbing, effectively killing it. Wish I could say that damaging behavior at National Parks was a new phenomena but apparently not.
Minute Geyser:
Minute Geyser spouts vigorously 1-3 feet above its crater. Early visitors waiting for stagecoaches amused themselves by tossing coins and other objects into the geyser.
Over time, this vandalism plugged the geyser’s plumbing, effectively killing it. No one can predict if Minute Geyser will ever display its former power again.
Geysers
Geysers have constrictions in their plumbing systems that prevent water from moving freely to the surface where heat would escape. Water beneath the constrictions creates a buildup of steam. Eventually the steam pushes water past the constrictions and the geyser erupts.
Color and Heat Lovers
Hydrothermal features are also habitats in which microscopic organisms survive and thrive. They are called thermophiles: “thermo” for heat and “phile” for lover.
Although they are too small to be seen with the naked eye, trillions are grouped together and appear as masses of color. They are nourished by energy and chemical building blocks.
Colorless and yellow thermophiles grow in the hottest water.
Orange, brown, and green thermophiles grow in cooler waters.
Imagine living in near-boiling temperatures, in hydrothermal features with the alkalinity of baking soda, or in water so acidic that it can burn holes in clothing. Microorganisms in Yellowstone need these extremes to survive.
Norris Geyser Basin
Norris Geyser Basin is one of the hottest and most acidic of Yellowstone’s hydrothermal areas. It is outside of the most recent Yellowstone caldera, but inside the first and largest caldera. It sits on the intersection of three major faults and is a very active earthquake area.
Each year, new hot springs and geysers appear while others become dormant. Geologic events trigger many of these changes. Even small earthquakes can alter hydrothermal behavior. This sudden activity is known as a “thermal disturbance” and can last a few days, or more than a week. Gradually, most features return to “normal.”
No one fully understands why this happens. Norris has the greatest water chemistry diversity among Yellowstone’s hydrothermal areas. The water chemistry changes as the water levels of underground hot water reservoirs fluctuates.
Although Norris is known for its acid features, it also have alkaline hot springs and geysers. As underground water and chemistry shift suddenly, they could contribute to dramatic changes in minerals and pH.
Use Caution in Hydrothermal Areas
- Stay on boardwalks and designated trails.
- Hydrothermal water can severely burn you.
- Never run, push, or shove.
- Supervise children at all times.
- Do not scratch hydrothermal mats.
You are responsible for your safety.
Think safety, act safely. Yellowstone is a dangerous place.
