• West Thumb Geyser Basin - Thumb Geyser is celebrated for its vibrant hues, which are a result of the thriving bacteria in the warm waters of the West Thumb Geyser Basin. In the mid-1970s, scientists were intrigued by a decrease in geyser activity, attributing it to factors such as slow underground pool refilling or changes in rock composition.
• Blue Funnel Spring - Blue Funnel Spring, once spanning 18 feet and maintaining temperatures between 172 and 182 degrees Fahrenheit, has experienced cooling and depletion over the past thirty years, with its waters now flowing into the nearby Abyss Pool.
• Abyss Pool - Discover Abyss Pool, inviting visitors to the observation deck for a closer look! Descending 53 feet into the earth, it stands as one of Yellowstone’s deepest hot springs, proudly holding this distinction.
• Fishing Cone - Fishing Cone, a geothermal feature in Yellowstone National Park, is rich in history. In the late 1800s, it was used as a natural “hot pot” where visitors cooked trout directly in its boiling waters—a unique yet dangerous practice that resulted in several fatalities.
