These are not like gushing geysers, but rather constantly changing formations made by hot, mineral-rich water. Jupiter Terrace used to flow a lot, even covering parts of the boardwalk. Mound Terrace was quiet for many years but has recently started flowing again, creating new patterns on the rock.

Gorgeous Canary Spring, one of my favorite spots on the Mammoth Hot Springs area of Yellowstone National Park. Some steps are involved with the boardwalk. Enjoy and make sure you bring a good camera!

These are easy hikes, some are accessible for handicapped persons and wheelchairs, but not all. Make sure you take the time to hike down the boardwalk to see the Canary Spring side (you can see from my photos, the lovely terraces that you can see close up).

The Mammoth Hot Springs are a collection of geothermal vents and springs that empty onto the hills surrounding the city of Mammoth. The mineral rich spring water leaves behind beautiful marble white structures called terraces, which look like staircases.

Hot, mineral rich water from a nearby spring flows down the ridge at Palette Springs, leaving behind stalactite like formations called thermophiles. The entire small hill looks like a staircase made of white and brown steps.
