Longest running primary succession monitoring program in the world?

If you are into ecology, science history, or National Parks, this is for you.

Our research trip/archaeological expedition to Glacier Bay is starting to come together.  In 1916, William Cooper established what I believe are now the oldest primary succession permanent plots in the world. When he put them in, summer of 1916, they were around 15-20 years old, just having emerged from glacial ice.  Now the ground is ~115-120 years old, and the plots are turning 100. 

We're going to attempt to rediscover those plots, which haven't been visited since the 1970's.  If we can, we can match our measurements and photographs with the rich history that Cooper, and later his student Lawrence, created when they repeatedly visited and photographed these plots over ~60 years.  The original maps are below, and we're getting scans of Cooper's original field book (and Lawrence's follow up books).  This work is supported by National Geographic and the National Parks Service.
