Fountain Paint Pot Tour



Sinter mounds beneath geysers have been forming for thousands of years.

Below Clepsydra you can see the vast amount of sinter that has deposited in this area. Sinter was first deposited in the Firehole Valley as glacier ice melted. It continues to accumulate at different rates depending on the chemistry of the water in each spring and the rate at which erosion removes it. The sinter mound beneath these geysers has been building for thousands of years.
