Coal mining moved out of the river valley and onto the prairie when Galt No. 1 Shaft (1888-1897) was built. Galt No. 2 Shaft (1889-1897) was sunk northeast of Shaft No. 1. Galt Shafts No. 3 (1890-1924) and No. 4 (1893-1924) followed, situated north of Shaft No. 1. Shaft mines differed from drift mines in that their entries were dug vertically down to the coal seam, normally about ninety meters deep in the Lethbridge coal field. Hoists were used to move men and coal up and down a shaft. The top two photos show Galt Mine No. 3 at Lethbridge. The next photo shows the hoisting machinery at mine No. 6 while the last shows a loaded coal car just hoisted out of Shaft No. 8 - Dates? Photographers?
