M3.5 earthquake in the Badlands


Just south of Rapid City.  The location doesn't transfer any more to Google Maps.  Pooey!  Doesn't matter, I just did this because it is such a great tourist spot.  Did the trip a thousand years ago when I took the sister's car from LA to Chicago.  The Wind Caves, or Whistling Cave is fantastic for a geophysicist.  It is such a huge volume that only exits at a small spot, so it was discovered by the steam whistle effect when the barometer changed.  They are still exploring it.
