The Silex Spring found in the Lower Geyser Basin of Yellowstone NP. Temperature is 193°F Dimensions 35.5x39.4 feet. Depth 27 feet. It is unknown when or by whom this colorful blue spring was named, but the name Silex may refer to the word silica. Some believe it may refer to the Silex coffee percolator. The spring boils occasionally and, periodically large bubbles of gas rise to the surface. The 1959 earthquake caused it to erupt and increased the flow. The discharge is now 75 to 100 gallons per minute. There are underground connections to Celestine Pool, a similar nearby hot spring.
