Big Gap School 1919 - 1954 south of Highway 599 on Range Road 73A in Alberta. Highway 599 runs east of Castor, Alberta. I was perusing Google and found this one by chance. I thought it was a school when I saw it on the satellite view and when I found the time to drive there it turned out to be Big Gap School.
The sign is overgrown and easy to miss. The building is in rough shape. I think cattle have been in it several times.
Behind the school was a foundation so there must have been another building like a teacherage.
