My mother, Alma (née McKay) Brennen, and her sister Verna McKay, attended Colt Lake School near Nokomis in the 1920s. I happened across a photograph of Aunt Verna in front of the school and, lo and behold, the sign board of the school is visible behind her (see below). The location of the school on your website is given as Sec. (?) Tsp 30, Rge 23, W2. We can see on the sign board the correct location: Section S.E. 25, Township 29, Range 23, West of 2nd Meridian.
