Installation of passive seismic stations is done

Sixty-three passive seismic stations are in the ground and recording and all field crews have returned to their home bases.  Seven more stations are to be added in a couple of weeks once a few additional permits are in hand and the snow melts at higher elevations.  A more complete summary, some photos and a map will be shortly forthcoming in a blog.  The next big push is the active seismic experiment to start in late July.  Rumor is that crews are starting to arrive in the area but details are so far sketchy.
