Click here for a map of Calgary and areas to the east. It opens in a new tab or window because you're going to need to look at it and read this post at the same time. You'll probably want to zoom in one or two levels - I'm just giving you the overview to start with.
Calgary is marked, and the light grey area around it is obviously the built-up area of the city proper. Then head east along Highway 1. All the rectangles of various shades of green are most likely fields. Then keep following Highway 1 southeast. See all those dark grey areas on both sides of but especially south of Highway 1? What are all those? Zooming in provides no insight. They look barren from these satellite pictures, but there are rivers running through them.

Is it possible they were taken while there was snow on the ground? Google maps/Google Earth uses a composite of satellite imagery - maybe snow-covered land was sub'd in to base imagery that had cloud cover on it.
It's especially deceptive though b/c the green in the images - especially the lower-res images - is a result of some form of photo enhancement.
Hmmm...the snow on the Rockies and in the Arctic looks whiter, but that might be because it's higher up and/or purer. (Unfortunately, I don't know anywhere on Google Maps where we can definitively find snow in a comparable environment.
And then there's areas like this (in the northeast of the original map, zoomed in a couple of levels) where there are very clearly delineated green rectangular fields in the middle of the grey.
