The first time Momma and I were overnighting at Trail Camp she spent all night listening to rockfall in some of the surrounding hillslopes (at first she thought it was thunder and we were in trouble.. then realized what it was... I in my comatose state was completely oblivious to any and all sounds).
Anyways... we dicussed it the next morning and wondering if it had anything to do with seismic activity in the area and when we got home she looked at the USGS site and sure enough there had been a "swarm" of small quakes in the area that night....
