My family and I drove past it on Friday and it was covered in rain clouds.  It erupted on a Sunday Morning.  We were flying from Seattle to Salt Lake so I could teach in Rock Springs on Monday.  Seattle was clear and Sunny even though we could see St. Helens erupting and spewing ash in the air from Tacoma, where we were staying. 

We got on the plane and flew over the Ash to Salt Lake and then drove to Rock Springs, WY.  When I woke up to get to work, there was ash on my car.

My daughter was in Kindergarten and flew around an exploding volcano this day.
