We stopped at Rockglen this past June (2012) on our way through southern Saskatchewan. We had something to eat and drink and were amazed that a village could survive in such an isolated area. Farming and ranching is likely what keeps the village going. I searched for Rockglen and came across a YouTube video of collected photos and memorabilia of Rockglen. It's 10 minutes long, so unless you're from the area you might find it a bit long. At the 7 minute mark, or so, are some great photos of Rockglen from a distance putting it's location in perspective.
One wooden grain elevator is still standing-- a visual reminder of days gone by.
