I took this photo on the way from the town of Banff to Lake Minnewanka in Banff National Park.
It is a simple picture showing the grass, trees, mountains and sky. I have a print of it on my wall and it looks nice.
If it suites your tastes you can use it as a desktop wallpaper.
Just click on the image to view the full size version. Then, right-click the full size version and amongst the options should be a “set as desktop wallpaper” option.
