Old weathered wooden hut standing alone in a green field under a cloudy sky in Alberta, Canada.

🌾🏡✨ A weathered wooden hut in the middle of a lush green field under a cloudy blue-gray sky. The structure appears aged and partially broken, with missing panels and open spaces where windows and doors once were. I kept seeing these in the fields all through Alberta but I haven't been able to determine exactly what they were used for. This was one of four identical huts, each with an upper and middle window and what looks like a ventilation hole at the bottom. Does anyone want to enlighten me with some details of what the use of these huts would have been?
