This is Jeff's "Introduction to Sagehen" slideshow that he shows to all Sagehen guests as part of their orientation. It encapsulates what's been going on at the field station for the past 55 years or so.

You can also download it as a Quicktime movie at sagehen-video.blogspot.com/2008/10/50-years-of-sagehen.html
