I was thumbing through one of my favorite picture collections the Barnard-Stockbridge collection at the University of Idaho http://www.lib.uidaho.edu/digital/barstock/all.html and came across a photo of the Hercules Mill in the Burke, Idaho area. It is just a neat building. I believe it is a stamp mill but I am not an exert on such things. But it has just a cool look. Thought I would share.

Sorry about not putting the actual photos up for some reason they only produce parts of the picture. I would have to down load them then upload them so I figured I would post the link.
