One of the presentations at the WSF Banquet was on the topic of prescribed burns, the presenter was Dave Finn with SRD and was about all the logistics, difficulties and plans they have for the future. Within that context Dave also presented to the participants a tool that they are utilizing and it is called the "Mountain Legacy Project" (

Apparently back near the turn of the 19th century and early 20th a series of stations were set up and photographs were taken from each station. These plates were recently rediscovered and have been the basis for repeat photos from the same stations to document the changes that have occurred over the last century.
Over the last couple days I've been looking at the site and it is interesting to go through the areas you recognize and check out the changes of the past 100 years.
Just thought I'd pass on the link.
