Sapphire Pool, one of the prettiest in Yellowstone, settled down to its placid former self after a violent episode in 1959. The Hebgen Lake earthquake turned the placid clear pool into a powerful, muddy geyser for years afterward. T. Scott Bryan writes,
"No spring in Yellowstone was more greatly affected by the 1959 earthquake than Sapphire. The day after the shocks the crater was filled with muddy water, constantly boiling with vigor. Four weeks later Sapphire began having tremendous eruptions. Fully 125 high and almost equally as wide, these eruptions were among the most powerful ever known in Yellowstone. At first, the intervals were as short as two hours, and each play lasted five minutes."
The eruptions enlarged the pool by several feet, destroying the geyserite "biscuits" around its crater that had given Biscuit Basin its name. Over time the eruptions became less intense and frequent. By 1971 all the muddiness was gone, and Sapphire again regained its pristine aqua color, as you see it today.
Change is the only constant in Yellowstone's hot springs. Just 100 yards to the east of Sapphire Pool (out of frame to the right of the photo) is an area where explosions have created and altered springs and geysers in the decades following 1902. Explosions as recent as 2006-2008 threw rocks and debris as far as 50 feet. Remnants of these explosions are visible from the boardwalk as you walk to Sapphire Pool. Geologists are keeping an eye on the area (see next photo of Black Opal Pool).
Pure and cool.

The Silent Pool is a small tree-lined, spring-fed lake between Dorking and Guildford in Surrey.
Legend has it that a woodcutter who lived in the forest had a son and a beautiful daughter named Emma. One day she was bathing in the lake when she heard a horse and rider approaching and, having no time to get out and dress, she waded deeper to cover herself. The rider tried to get her to leave the water but she refused. He rode in after her and her cries for help brought her brother to her aid. Brother and sister drowned and their ghosts are said to haunt the lake and Emma is said to be seen floating on the water. Legend further has it that the rider was the future King John who succeeded his brother Richard to the throne in 1199.
No sign of any ghosts or floating damsels during my visit but it is a most beautiful and serene place.
