We get a lot of earthquakes in Wyoming. Most are near the very seismically active area near Yellowstone. That's why it was a bit of a surprise to learn that an earthquake just occurred in southern Wyoming near Saratoga.
I doubt that even the pronghorn that were grazing right above this were aware that anything happened, but there was a minor earthquake west of Casper Sunday morning.
Thursday's Idaho earthquake felt in Utah & Wyoming. The quake happened around 8:30 and was only about 4.3 in magnitude. Some were shaken, but not stirred.
