West Thumb Geyser Basin
Abyss Pool is one of the deepest hot springs in the park, descending 53 feet (16 m).
Hot springs are the most common hydrothermal features in Yellowstone. Their plumbing has no constrictions.
Superheated water cools as it reaches the surface, sinks, and is replaced by hotter water from below.
This circulation prevents water from reaching the temperature needed to set off an eruption.
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.
