After the abrupt termination of my 2006 “Searching“, I finally had the opportunity to peruse the Fred Harvey Collection at Northern Arizona University Cline Library. I barely finished going through the dozen boxes of material I had selected to review in the 18 hours I had allotted. Like all archival searches, there were boxes of irrelevant materials, lots of stuff I had seen before, some interesting although irrelevant tidbits of information, and a few gems of new, relevant data. I even found the source of some oft-cited, but undocumented facts.
Most of the material dated from after the purchase of Fred Harvey by Amfac in 1968, a period I have not paid much attention to since most of the Fred Harvey postcard views in my manuscript The Grand Canyon: A Fred Harvey Postcard History pre-date World War II. Some of the most relevant materials were letters from a blacksmith hired to recreate the bear trap for Hermit’s Rest, along with numerous other items.
That means the bear trap in 
the picture below is not the one on the postcard. No real surprise given the span of 80 years, but it’s nice to have proof of one’s suspicions. 
Be sure to check out notes on my previous trips in search of Fred Harvey postcard views. All can be accessed from my homepage http://trailsandtreasures.com/index.htm.
It’s a pity that people don’t realize the importance of this information. Thanks for posing it.
