Seismograph Pool
Description
Seismograph and Bluebell pools used to be known as the "Blue Pools." After the 1959 Hebgen Lake earthquake, which measured 7.5 on the Richter scale, the pools were renamed. At West Thumb, no one recorded the nature of the changes caused by the quake, but perhaps someone thought Seismograph Pool somehow "registered" the earthquakes. These days, Seismograph is sometimes muddy—but not from earthquakes. The mud comes from the runoff of nearby mud pots.
