BRONZE SPRING, like so many hot springs, lives a double life. It officially is named a ‘spring’, but it also plays as a geyser on occasions. Bursting eruptions can reach as high as 15 feet – but more often than not, the eruptions happen on a much smaller scale of a foot or two high at most. Eruptions are rare and were only reported one day in 2013, 2014, 2018, 2019 and 2020. If you happen to see a splashing eruption of Bronze, please let the ranger in the Visitor’s Center know.

WATCH FOR: Orange microbes growing in Bronze indicating that it’s too cool for the thermal feature to even think about erupting. When you don’t see any colorful microbes and the water looks blue or clear, well – that means it could be active either as a geyser or simply as a cyclic spring (water levels drop some and then rise to overflow and then repeats the cycle).
