Hi Michael. I am a frequent visitor as well and I agree they are not very far apart and you get a nice view of Mount St. Helens when you hike up Rainier. However, the recent activity at St. Helens hasn't been showing up on the Longmire seismo. The other seismos at Rainier tend to pick up just about everything including rockfalls, but Longmire doesn't normally show those events. I'm just curious as to what's causing it or if it's even good data. Thanks for your input!
