There were 4 elevators at Munson, Alberta... which is located north of Drumheller on the CN main line to Saskatchewan.
This elevator was actually located east of Munson just east of Highway 9 at Dinosaur Junction, which was the junction of the two Canadian National Lines.... one which continued onto Saskatchewan, while the other headed north to Stettler and Camrose. This elevator was a tricky one... not because it was complex... but because there were NO pictures of it anywhere. I finally found a pic from a family friend near Munson... and finally got it done!
This photo of Munson's three elevators is from Lynda Swanson's Endangered Species series. These elevators were torn down in the late 1990's.
Here are my three elevators in a similar layout... the Pioneer, Alberta Wheat Pool and United Grain Growers (UGG).
This would be looking at the elevators from an aerial viewpoint... actually it is on my parents kitchen table! This would looking SW... east is to the left, west to the right
