This is from GettyImages. It is a circa 1920s photo by photographer Darius Kinsey (1869-1945). The GettyImages site says Kinsey, “was a photographer active in western Washington State from 1890 to 1940. He is best known for his images of loggers and all phases of the region’s lumber industry.”

A cleansed look at the primitive camp settings where this dangerous outdoor work of many hours took place. How grateful we are to these hard working pioneers.
Thanks, Margaret. You are correct. Logging was and still is the most dangerous job in America. (http://newsfeed.time.com/2014/01/15/these-are-the-top-10-most-dangerous-jobs-in-the-u-s/) There are more ways to die in the woods that I’m sure Kesey’s portrayal in Sometimes a Great Notion is based on an actual death.
